Abstract: It is very important to study and analyze the air distribution and thermal effects of the conditioned air that is supplied to the cabin. This is because all the passengers should be comforted with the ac system. The ac system is one of the most popular features of the automobile industry. In this work, a numerical investigation is carried out using the commercial software ANSYS about the flow and thermal analysis of the cabin air circulation. We had created a 3d model of the maruti 800 car using design modeler and it is analyzed using the FLUENT software. Contours of velocity and temperature distribution are studied in detail. Four different combinations like front vent, front and rear vent, front and rear side vent, front and rear top vent are created and analyzed. The best configuration is find out from the temperature and velocity analysis.
