It is open-source and released under the Received in revised form 17 August 2017 same GNU General Public License (GPL) as OpenFOAM. The source code is released as a publicly open Accepted 25 September 2017 software repository that includes detailed documentation and tutorial cases. Since mdFoam+ is designed Available online 23 October 2017 entirely within the OpenFOAM C++ object-oriented framework, it inherits a number of key features. The Keywords: code is designed for extensibility and flexibility, so it is aimed first and foremost as an MD research tool, OpenFOAM in which new models and test cases can be developed and tested rapidly. Implementing mdFoam+ in Molecular dynamics OpenFOAM also enables easier development of hybrid methods that couple MD with continuum-based MD solvers. Setting up MD cases follows the standard OpenFOAM format, as mdFoam+ also relies upon Computational fluid dynamics the OpenFOAM dictionary-based directory structure. -

The One-Way FSI Method Based on RANS-FEM for the Open Water Test of a Marine Propeller at the Different Loading Conditions
Journal of Marine Science and Engineering Article The One-Way FSI Method Based on RANS-FEM for the Open Water Test of a Marine Propeller at the Different Loading Conditions Mobin Masoomi 1 and Amir Mosavi 2,3,* 1 Department of Mechanical Engineering, Babol Noshirvani University of Technology, Babol, Iran; [email protected] 2 Faculty of Civil Engineering, Technische Universität Dresden, 01069 Dresden, Germany 3 John von Neumann Faculty of Informatics, Obuda University, 1034 Budapest, Hungary * Correspondence: [email protected] Abstract: This paper aims to assess a new fluid–structure interaction (FSI) coupling approach for the vp1304 propeller to predict pressure and stress distributions with a low-cost and high-precision approach with the ability of repeatability for the number of different structural sets involved, other materials, or layup methods. An outline of the present coupling approach is based on an open- access software (OpenFOAM) as a fluid solver, and Abaqus used to evaluate and predict the blade’s deformation and strength in dry condition mode, which means the added mass effects due to propeller blades vibration is neglected. Wherein the imposed pressures on the blade surfaces are extracted for all time-steps. Then, these pressures are transferred to the structural solver as a load condition. Although this coupling approach was verified formerly (wedge impact), for the case in-hand, a further verification case, open water test, was performed to evaluate the hydrodynamic part of the solution with an e = 7.5% average error. A key factor for the current coupling approach is Citation: Masoomi, M.; Mosavi, A. -
Wind Field Simulation in a Wind Farm Using Openfoam and Actuator Line Model
ParCFD'2019 31st International Conference on Parallel Computational Fluid Dynamics May-14-17 2019, Antalya TURKEY WIND FIELD SIMULATION IN A WIND FARM USING OPENFOAM AND ACTUATOR LINE MODEL Huseyin Can Onel∗ & Dr. Ismail H. Tuncery ∗ Middle East Technical University (METU) Department of Aerospace Engineering 06800 Ankara, TURKEY e-mail: [email protected] yMiddle East Technical University (METU) Department of Aerospace Engineering 06800 Ankara, TURKEY e-mail: [email protected] - Web page: http://www.ae.metu.edu.tr/tuncer/ Key words: Aerospace applications, Wind turbine, HAWT, Actuator Line Model, Wake calculation Abstract. In this study, a horizontal axis wind turbine (HAWT) is modeled using so called Actuator Line Model (ALM), where full resolution of boundary layer over turbine blades is not needed and hence computation is cheaper. Results are validated against other numerical and experimental studies as well as panel method (XFOIL) and Blade Element Momentum Theory (BEMT) results which are still widely employed in today's wind energy industry. Important simulation and operation parameters and their effects on accuracy are discussed. It is concluded that within a certain range of tip speed ratios, ALM gives acceptable results and is a promising model for full-scale wind farm simulations to estimate energy production. 1 INTRODUCTION Market share of renewable energy grows at ever highest rates and wind turbine and wind farm design processes becomes more sophisticated with the advancements in computation technologies. There are two main design problems in wind energy: • Design of an individual wind turbine at its ideal operation conditions, where classical methods like 2D airfoil theory, potential flow theory and Blade Element Momentum Theory (BEMT) are still widely used, • Design of a complete wind farm, in which statistical meteorological data is used for macro-siting and simple analytical or empirical methods are used for micro-siting. -

In total, Philippidis recorded 232 settlements, in a credible manner, as demonstrated by comparison with information from other sources of the period. The examination of this data reveals the very strong presence of mainly Christian settlements of small dimensions, not exceeding 100 homes, located at relatively low elevations. Also notable is the presence of a few cities exceeding 1000 homes of largely Muslim population, as well as “islets” of settlements with Muslim or mixed populations in flatlands. The settlement complex was supported by monasteries, berths, bazaars and inns, which constituted functional components of the financial activities. This text is part of a study being conducted at the Institute for Neohellenic Research concerning the history of settlements in Greece (fifteenth- twentieth centuries). In 1815 Argyris Philippidis, brother of Daniel Philippidis, the co-author of Νεωτερικῆς Γεωγραφίας [Modern geography], wrote a manuscript entitled Μερικὴ Γεωγραφία [Partial geography], which remained unpublished until the end of the 1970s.1 In this manuscript A. -

Abstract: In the ergonomic design of wearable products such as an oxygen mask, systematic design methods including the analysis of anthropometric information, evaluation of fit, and product design need to utilize 3D human scan data. The present study intends to develop a virtual fit analysis method that generates an ergonomic shape of an oxygen mask for fighter pilots based on 3D facial scans. The proposed virtual fit analysis method enables iteratively to revise the shape of an oxygen mask until an appropriate level of fit between the mask and a group of pilot faces is achieved. The proposed method of virtual fit analysis and design optimization was applied to find ergonomic shapes of oxygen masks for four size categories (small narrow, medium narrow, medium wide, and large wide) to accommodate 336 pilots of the Republic of Korea Air Force.
