  • CHAPTER 20 Wind Turbine Noise Measurements and Abatement
    CHAPTER 20 Wind turbine noise measurements and abatement methods Panagiota Pantazopoulou BRE, Watford, UK. This chapter presents an overview of the types, the measurements and the potential acoustic solutions for the noise emitted from wind turbines. It describes the fre- quency and the acoustic signature of the sound waves generated by the rotating blades and explains how they propagate in the atmosphere. In addition, the avail- able noise measurement techniques are being presented with special focus on the technical challenges that may occur in the measurement process. Finally, a discus- sion on the noise treatment methods from wind turbines referring to a range of the existing abatement methods is being presented. 1 Introduction Wind turbines generate two types of noise: aerodynamic and mechanical. A tur- bine’s sound power is the combined power of both. Aerodynamic noise is gener- ated by the blades passing through the air. The power of aerodynamic noise is related to the ratio of the blade tip speed to wind speed. The mechanical noise is associated with the relevant motion between the various parts inside the nacelle. The compartments move or rotate in order to convert kinetic energy to electricity with the expense of generating sound waves and vibration which is transmitted through the structural parts of the turbine. Depending on the turbine model and the wind speed, the aerodynamic noise may seem like buzzing, whooshing, pulsing, and even sizzling. Downwind tur- bines with their blades downwind of the tower cause impulsive noise which can travel far and become very annoying for people. The low frequency noise gener- ated from a wind turbine is primarily the result of the interaction of the aerody- namic lift on the blades and the atmospheric turbulence in the wind.

  • Industrial Aerodynamics
    INDUSTRIAL AERODYNAMICS Unit I Wind Energy Collectors INTRODUCTION Air Movement Wind Air Current Circulation The horizontal movement of air along the earth’s surface is called a Wind. The vertical movement of the air is known as an air current. Winds and air current together comprise a system of circulation in the atmosphere. TYPES OF WINDS On the earth’s surface, certain winds blow constantly in a particular direction throughout the year. These are known as the ‘Prevailing Winds’. They are also called the Permanent or the Planetary Winds. Certain winds blow in one direction in one season and in the opposite direction in another. They are known as Periodic Winds. Then, there are Local Winds in different parts of the world. 1. Planetary Winds: There are three main planetary winds that constantly blow in the same direction all around the world. They are also called prevailing or permanent winds. 1.Trade Winds: Blow from the subtropical high pressure belt towards the Equator. They are called the north-east trades in the northern hemisphere and south-east trades in the southern hemisphere. 2.Westerly winds: Blow from the same subtropical high pressure belts, towards 60˚ S and 60˚ N latitude. They are called the sought Westerly wind sin the northern hemisphere and North Westerly winds in the southern hemispheres. 3.Polar Winds Blow from the polar high pressure to the sub polar low pressure area. In the northern hemisphere, their direction is from the north-east. In the southern hemisphere, they blow from the south-east. 2. Periodic Winds These winds are known to blow for a certain time in a certain direction - it may be for a part of a day or a particular season of the year.

  • Intercomparison of Planetary Boundary-Layer Parametrizations in the WRF Model for a Single Day from CASES-99
    Boundary-Layer Meteorol (2011) 139:261–281 DOI 10.1007/s10546-010-9583-z ARTICLE Intercomparison of Planetary Boundary-Layer Parametrizations in the WRF Model for a Single Day from CASES-99 Hyeyum Hailey Shin · Song-You Hong Received: 5 June 2010 / Accepted: 22 December 2010 / Published online: 20 January 2011 © Springer Science+Business Media B.V. 2011 Abstract This study compares five planetary boundary-layer (PBL) parametrizations in the Weather Research and Forecasting (WRF) numerical model for a single day from the Coop- erative Atmosphere-Surface Exchange Study (CASES-99) field program. The five schemes include two first-order closure schemes—the Yonsei University (YSU) PBL and Asymmet- ric Convective Model version 2 (ACM2), and three turbulent kinetic energy (TKE) closure schemes—the Mellor–Yamada–Janji´c (MYJ), quasi-normal scale elimination (QNSE), and Bougeault–Lacarrére (BouLac) PBL. The comparison results reveal that discrepancies among thermodynamic surface variables from different schemes are large at daytime, while the vari- ables converge at nighttime with large deviations from those observed. On the other hand, wind components are more divergent at nighttime with significant biases. Regarding PBL structures, a non-local scheme with the entrainment flux proportional to the surface flux is favourable in unstable conditions. In stable conditions, the local TKE closure schemes show better performance. The sensitivity of simulated variables to surface-layer parametrizations is also investigated to assess relative contributions of the surface-layer parametrizations to typical features of each PBL scheme. In the surface layer, temperature and moisture are more strongly influenced by surface-layer formulations than by PBL mixing algorithms in both convective and stable regimes, while wind speed depends on vertical diffusion formulations in the convective regime.

  • Wind Shear and Turbulence on Titan : Huygens Analysis
    Wind Shear and Turbulence on Titan : Huygens Analysis Ralph D. Lorenz* Johns Hopkins University Applied Physics Laboratory, 11100 Johns Hopkins Road, Laurel, MD 20723, USA * Corresponding author tel: +1 443 778 2903 fax: +1 443 778 8939 email: [email protected] Highlights: • Wind shear during Huygens descent was within predicted range • Shear reached terrestrial aviation 'Light Turbulence' levels • Doppler and probe tilt indicate ~0.2 m/s fluctuations in lowest 4km • Simple AR(1) model reproduces observed turbulence characteristics Icarus Keywords : Titan, atmosphere ; Atmospheres, dynamics ; Meteorology Abstract Wind shear measured by Doppler tracking of the Huygens probe is evaluated, and found to be within the range anticipated by pre-flight assessments (namely less than two times the Brunt-Vaisala frequency). The strongest large-scale shear encountered was ~5 m/s/km, a level associated with 'Light' turbulence in terrestrial aviation. Near-surface winds (below 4km) have small-scale fluctuations of ~0.2 m/s , indicated both by probe tilt and Doppler tracking, and the characteristics of the fluctuation, of interest for future missions to Titan, can be reproduced with a simple autoregressive (AR(1)) model. The turbulent dissipation rate at an altitude of ~500m is found to be 16 cm2/sec3, which may be a useful benchmark for atmospheric circulation models. 1. Introduction Wind shear, the spatial gradient of wind speed, is of significant practical interest in planetary exploration and in terrestrial aviation. A vehicle moving relative to the air will encounter time-varying winds which can excite movements which may blur images (Karkoschka, 2016), affect the strength of the radio signal (Dzierma et al., 2007), or cause air passengers to spill their drinks.

  • Wind Tunnel Tests on Schooner Rigs and Their Use in Performance Prediction by Vpp Calculations
    WIND TUNNEL TESTS ON SCHOONER RIGS AND THEIR USE IN PERFORMANCE PREDICTION BY VPP CALCULATIONS by I.M.C.Campbell and G. Dijkstra HISTORICAL BACKGROUND A tour around the maritime museums of the world will reveal the rich history of Schooner rigs used to propel commercial sailing vessels. Just a few examples are; the Schooners built in Dartmouth in the UK to ply the coal and fruit trade to the Mediterranean; those that sailed out of Paimpol in Brittany to fish off Iceland; and others that sailed from East coast ports in the USA to fish off the Grand Banks. It was clearly a universally successful working rig that also found favour in cruising and racing yachts, with America winning a race around the Isle of Wight almost 150 years ago to take the “America’s Cup” to the New York Yacht Club. In recent years a number of devotees have kept the Schooner rig alive and well through restoration, re-build and new-build projects. This paper describes tests conducted with wind tunnel models with the aim of continuing the development of the Schooner rig. TECHNICAL BACKGROUND It can be difficult to fit all the required sail area on to a single mast for a large yacht. Small sloop-rigged yachts can be scaled up to larger sizes but to have the same scale performance, according to Froude scaling, the wind speed should increase with the square root of scale. This is less likely to occur in practice, since for example a large and small yacht sailing together operate in the same wind speed, except for the increase with mast height due to the wind gradient.

  • Sound from Wind Turbines in Forest Areas – Are the Sound Propagation Models Used Today Adequate?
    STS 09007 Examensarbete 30 hp Januari 2009 Sound from wind turbines in forest areas – Are the sound propagation models used today adequate? Mattias Wondollek Abstract Sound from wind turbines in forest areas Mattias Wondollek Teknisk- naturvetenskaplig fakultet UTH-enheten The Swedish model results in higher predicted sound levels, compared to international standard, which makes it more difficult for Swedish wind power Besöksadress: developers to place their turbines optimal at forest sites. The aim of this study is to Ångströmlaboratoriet Lägerhyddsvägen 1 investigate the reasons for that, but also to cast more light on the potential forestal Hus 4, Plan 0 effect on sound emission and propagation from wind turbines. Postadress: The study reveals that the main reason behind the differences in predicted sound Box 536 751 21 Uppsala levels when comparing the models is due to a roughness correction formula in the Swedish model, returning an overestimated sound power level for roughness length’s Telefon: larger than 0.05 m, and vice versa. 018 – 471 30 03 Telefax: Another important finding is that the end result is not only affected by the differences 018 – 471 30 00 between the models, but can also be originated to the interpretations made by software developers and wind power developers. The Swedish land based model is a Hemsida: very simplified model, only suitable for non-refractive meteorological condition and http://www.teknat.uu.se/student flat hard ground with no obstacles or vegetation, when compared to more advanced sound propagation models such as Nord2000. Overall forests probably have a damping effect on sound emission and sound propagation from wind turbines, especially for frequencies over 1000 Hz and during meteorological conditions favorable to propagation.

  • ORC Speed Guide Explanation
    OFFSHORE RACING CONGRESS ORC Speed Guide Explanation 1. INTRODUCTION The ORC Speed Guide is a custom-calculated manual for improving performance for an individual boat. It is intended to augment, not to replace, other books and articles which offer general suggestions for the improvement of sailing performance by providing you with specific performance targets for your boat. This Speed Guide will be of interest to both beginners and more experienced sailors who want to have a deeper understanding of the relationships between speed and factors such as sail selection, wind speed, and wind angle. The speed predictions for the individual boats which are central elements of the Speed Guide are derived in two steps: First, the hull and appendages are measured by use of an electronic device so as to put the hull lines into the computer data bank. The other elements of measurement - the rig and sail dimensions, the flotation and stability data, etc. - are also added to the data bank for this one boat. Second, a series of complex calculations are made to find the boat speeds at which all of the elements of drag come into equilibrium with the drive provided by the sails. This is what constitutes the Velocity Prediction Program, or VPP, which is annually updated and improved by ORC. The utility of these VPP-generated predictions and how they relate to the measured performance on board your boat will greatly depend on the steadiness of the sailing conditions, the abilities of the helmsman and crew, and the accuracy of the instrumentation on board. While you cannot necessarily control the weather, the skills of your team can be improved as well as the calibration of the instruments as described in Appendix C of this Guide.
