Thermal and Air Flow Analysis of Shelters Using CFD

The shelters are like a housing structures used for the army for sheltering in terrain places. These shelters are mounted over the army vehicles which are subjected to static, dynamic and thermal loads due to vehicle transportation in all kinds of terrains. The shelters are subjected to a different thermal loads due to seasonal externally temperatures and inside there are heat dissipating elements. The objective is to maintain the temperature inside the shelter at around 27 degree centigrade for which the CFD analysis is performed. This study uses the Fluent software to evaluate the indoor thermal environment of Shelter and the analysis is to perform Thermal and air flow studies for prediction of the temperatures when the components are dissipating heat inside the shelter. Shelter contains four Panels and one air pre heater which dissipate heat. The shelter subjected to an extreme operating temperature -30 to +55 centigrade and there is need of AC’s for temperature control. In this study the location and number of AC's required and on off conditions are studied using Fluent solver for the temperature predictions.The steady state and transient analysis is performed using Fluent.
