thermal modeling of an automotive cabin was performed in this paper to predict the inside cabin air temperature. to implement this task, thermal and ventilation loads were estimated and the mass and energy balance conservation equations for dry air and water vapor with considering a new parameter (air circulation ratio) as well as the balance equations of internal components of a cabin were der...

The present study aims to investigate the analysis of stress, strain, displacement, and electrical potential of a thick hollow cylinder made of FGPM under mechanical and thermal loads. Distribution of mechanical property of material is considered along the shell stick through the power distribution function. Thermal loads have been taken to signify the difference of temperature between outer an...

This paper presents an energy management strategy to supply residential load by hybrid fuel cell power plant (FCPP). Economical fuel cell (FC) model includes thermal load, local electrical load, operational cost, startup cost and different tariffs on electricity during the day hour is discussed.  Several Strategies have been presented for supplying residential load (electrical and thermal loads...

Autodesk Ecotect TM is an environmental analysis software which according to the U.S. Department of Energy, has not been validated yet. Therefore, the objectives of this research were to validate accuracy of Ecotect TM for thermal and daylighting simulations of buildings and provide recommendations to the Architecture, Engineering and Construction community on application of Ecotect TM . Analys...

Integral abutment bridges (IABs) have many advantages over conventional bridges in terms of strength and maintenance cost. Due to the integrity of these structures uniform thermal and seismic loads are known important ones on the structure performance. Although all bridge design codes consider temperature and earthquake loads separately in their load combinations for conventional bridges, the t...

The effects of task-ambient (TA) air-conditioning systems on the air-conditioning loads in small and large spaces and the thermal comfort of occupants were studied using computational fluid dynamics (CFD), pedestrian-behavior model, and refrigerating-cycle simulator. Task areas were set up to match with crowdedness as predicted by the pedestrian-behavior simulations. Subsequently, a variety of ...

the dual fuel engines at part loads inevitably suffer from lower thermal efficiency and higher carbon monoxide and unburned fuel emission. this work is carried out to investigate combustion characteristics of a dual fuel (dieselgas) engine at part loads, using a single zone combustion model with detailed chemical kinetics for combustion of natural gas fuel. the authors developed software in whi...

A significant step in the design of Heating, Ventilating, Air Conditioning, and Refrigeration (HVAC-R) systems is to calculate room thermal loads. The heating/cooling loads encountered by the room often vary dynamically while the common practice in HVAC-R engineering is to calculate the loads for peak conditions and then select the refrigeration system accordingly. In this study, a self-adjusti...
