Thermal comfort is very essential for the occupants in the residential building without air-conditioning system in the hot and arid climatic regions. In this study, the thermal comfort prevailed inside the room with window openings at their adjacent walls was analyzed under various wind directions by computational fluid dynamic technique. The CFD simulation was validated with the experimental results obtained from wind tunnel test rig and network model and found that it is having a good agreement. The room with single window opening at the adjacent walls was investigated under various wind directions and based on their prevailed uncomforted zones, the window opening at the windward side wall was splited in to multiple vents as double and triple vent system without changing window opening area. From this study, it was identified that the triple vent system reduces the indoor temperature and predicted mean vote by 0.3 and provides improved uniform thermal comfort.
Key words: Computational fluid dynamics, multiple vent system, natural ventilation, predicted mean vote, thermal comfort, ,
