  • Comparing Modes of Operation for Residential Ceiling Fans to Achieve Thermal Destratification 12/15/2014
    WHITE PAPER COMPARING MODES OF OPERATION FOR RESIDENTIAL CEILING FANS TO ACHIEVE THERMAL DESTRATIFICATION 12/15/2014 Credit: Thomas Lesser, Research Engineer Jay Fizer, Research-and-Development Laboratory Manager Christian Taber, Applications Engineer Overview Conventional wisdom says to reverse the direction of a ceiling fan’s rotation in the winter. Heat rises, filling a room with warm air from the top down and requiring heaters to run longer to achieve a desired ambient air temperature at the height of the thermostat and occupants. Running a fan in reverse helps move this heat across the ceiling and down the walls, recirculating the warm air through the space. Fans have been capable of reversing direction for decades, and legislation was passed in 2007 that required ceiling fans to have a reverse function. The logic behind reversing a fan is simple: since running fans in the forward direction creates a cooling effect through air movement, reversing those fans helps recirculate heat in the winter without creating an uncomfortable cooling draft. Big Ass Fans is aiming to prove that there’s a more energy-efficient and comfortable way to address heating conservation with ceiling fans. This study compared the effects of paddle fan reversal with Big Ass Fans’ Haiku ceiling fan, operating in the forward direction at lower speed settings than a paddle fan. Hypothesis Primary Hypothesis: Reverse Operation Is Less Efficient Reversing a paddle fan is not the best way to efficiently recirculate heat and fight heat stratification. A Haiku ceiling fan, operating in the forward direction, can destratify a room more efficiently than paddle ceiling fans operating in reverse.

  • Comparison of Computational Results with a Low-G Nitrogen Slosh And
    Comparison of Computational Results with a Low-g, Nitrogen Slosh and Boiling Experiment Mark. E. M. Stewart1 VPL at NASA Glenn Research Center, Cleveland, Ohio, 44135 Jeffrey P. Moder2 NASA Glenn Research Center, Cleveland, Ohio, 44135 This paper compares a fluid/thermal simulation, in Fluent, with a low-g, nitrogen slosh and boiling experiment. In 2010, the French Space Agency, CNES, performed cryogenic nitrogen experiments in a low-g aircraft campaign. From one parabolic flight, a low-g interval was simulated that focuses on low-g motion of nitrogen liquid and vapor with significant condensation, evaporation, and boiling. The computational results are compared with high-speed video, pressure data, heat transfer, and temperature data from sensors on the axis of the cylindrically shaped tank. These experimental and computational results compare favorably. The initial temperature stratification is in good agreement, and the two-phase fluid motion is qualitatively captured. Temperature data is matched except that the temperature sensors are unable to capture fast temperature transients when the sensors move from wet to dry (liquid to vapor) operation. Pressure evolution is approximately captured, but condensation and evaporation rate modeling and prediction need further theoretical analysis.

Regarding utilization of Thermal stratification in the storage tank, some unbalancing for thermal stratification would emerge during charging and discharging. In this project, a Computational Fluid Dynamics investigation on Ecovat is performed to determine the effects of inlet hot water, thermocline thickness, temperature difference between inlet water and existing water in tank, and position of diffusers on the mixing and thermocline formation, which influenced the performance of Ecovat systems and thermal stratification. Furthermore, the CFD model would be Proposed for the the whole Ecovat system (Diffusers and Tank) for the first time and this model can be utilized to simulate the Ecovat with custom dimensions based on the client’s requirements. CFD Simulation will demonstrate how the Ecovat system will work in real operational cases. ii | P a g e Table of Contents Abstract ............................................................................................................................... ii Table of Contents ............................................................................................................... iii List of Figures ....................................................................................................................

  • Evaluation of a Stratified Multi-Tank Thermal Storage for Solar Heating Applications
    EVALUATION OF A STRATIFIED MULTI-TANK THERMAL STORAGE FOR SOLAR HEATING APPLICATIONS by Cynthia Ann Cruickshank A thesis submitted to the Department of Mechanical and Materials Engineering In conformity with the requirements for the degree of Doctor of Philosophy Queen’s University Kingston, Ontario, Canada June, 2009 Copyright © Cynthia Ann Cruickshank, 2009 Abstract A novel multi-tank thermal energy storage (TES) was evaluated experimentally and numerically. The multi-tank storage is based on the interconnection of standard hot water storage tanks by a single charge flow loop. Each tank is charged through a thermosyphon loop and natural convection heat exchanger (NCHE). Both series- and parallel-connected configurations were investigated and results show that high degrees of stratification can occur. To predict the performance of the series- and parallel-connected multi-tank TES, a numerical model was developed and implemented in the TRNSYS simulation environment. Laboratory tests were also conducted to measure the unit’s performance under charge conditions representative of combinations of clear and overcast days. The effects of rising and falling charge loop temperatures and power levels on storage temperatures and heat transfer rates were studied and indicated that sequential stratification was achieved in the series-connected storage. Under certain conditions, reverse flow through the thermosyphon loops was identified, leading to destratification and carry-over of heat to the downstream storage tanks. Consequently, a new model was developed and showed to model reverse thermosyphon operation. A subsequent analysis showed that these effects could be minimized by careful system design. To quantify the relative benefits of the sequentially stratified TES, values of exergy stored versus time were determined and compared against fully stratified and fully mixed storages.

  • Zero Gravity Cryogenic Vent System Concepts for Upper
    ZERO GRAVITY CRYOGENIC VENT SYSTEM CONCEPTS FOR UPPER STAGES Robin H. Flachbart James B. Holt Leon J. Hastings Space Transportation Directorate NASA- Marshall Space Flight Center ABSTRACT The capability to vent in zero gravity without resettling is a technology need that involves practically all uses of sub-critical cryogenics in space, and would extend cryogenic orbital transfer vehicle capabilities. However, the lack of definition regarding liquid/ullage orientation coupled with the somewhat random nature of the thermal stratification and resulting pressure rise rates, lead to significant technical challenges. Typically a zero gravity vent concept, termed a thermodynamic vent system (TVS), consists of a tank mixer to destratify the propellant, combined with a Joule-Thomson (J-T) valve to extract thermal energy from the propellant. Marshall Space Flight Center's (MSFC's) Multipurpose Hydrogen Test Bed (MHTB) was used to test both spray-bar and axial jet TVS concepts. The axial jet system consists of a recirculation pump heat exchanger unit. The spray-bar system consists of a recirculation pump, a parallel flow concentric tube heat exchanger, and a spray-bar positioned close to the longitudinal axis of the tank. The operation of both concepts is similar. In the mixing mode, the recirculation pump withdraws liquid from the tank and sprays it into the tank liquid, ullage, and exposed tank surfaces. When energy extraction is required, a small portion of the recirculated liquid is passed sequentially through the J-T expansion valve, the heat exchanger, and is vented overboard. The vented vapor cools the circulated bulk fluid, thereby removing thermal energy and reducing tank pressure.
