... such as wool, polystyrene, wood fiber, cotton denim, etc. This article presents the modelling and simulation results on performance of microchannels in a typical building wall to provide dynamic thermal resistance for the building envelop. The simulations are performed for aluminum microchannels with air...

... and expands the float’s mission time. For this purpose, we developed a model consisting of hydraulic and electrical systems, designed to provide the electrical power needed by the UUV. The hydraulic and electrical systems are implemented using MATLAB-Simulink. The model developed can provide 13.66 kJ...

..., a common problem with the current lineup of programs is that they require extensive inputs for material properties and usage loads; this results in spending extensive amounts of time performing model calibration and having to adjust multiple values (sometimes hundreds) to bring a model in alignment...

...-dimensional numerical simulation model to investigate the thermal performance of a single and double U-tube embedded in the borehole. The water was chosen as a thermal fluid carrier and circulated in the borehole heat exchanger at a mass flow rate range of (0.14–0.34) kg/s and inlet temperature of (33) °C...

...COMPARISON AND IMPLEMENTATION OF THERMALLY MASSIVE WALL AND ROOF MODELS FOR USE IN SIMPLIFIED BUILDING ENERGY MODELS Christopher Fernandez and Sheldon Jeter Georgia Institute of Technology Atlanta, GA, USA ABSTRACT An increasing trend in building energy simulations is to use simplified models...

..., a detailed systems performance model of the engine generator, its heat recovery exchangers, the steam driven absorption chiller, a ventilation and air dehumidification unit, and multiple fan coil cooling/heating units has been programmed making use of TRNSYS to evaluate the utilization of the heat from...

... 10 01 2011 The main propose of this research is providing a tool for suitable modeling, increase efficiency and decrease construction cost of solar absorption chiller. At first, the solar absorption chiller is modeled by the thermodynamic laws. Then, this model is converted to the new...

... conditions. Energy storage rates and temperature profiles were experimentally measured during charge periods, and the effects of reverse thermosyphoning were quantified. A further aspect of this study was to empirically derive performance characteristics and to develop numerical models to predict...

... conversion efficiency. The energy harvester is simple, compact, and insensitive to excitation frequency. Initial prototypes have demonstrated power densities and specific powers many multiples greater than the best-performing, commercial vibration harvester. We have also developed a validated computer model...

... were conducted on a specially instrumented prototype to characterize its performance in terms of temperature stratification, heat transfer and energy storage rates. Based on these tests, a computer model of a complete multi-tank solar thermal system was created. With this model, the performance...
