Investigation of Air Circulation and Temperature Distribution in Car Compartment

Abstract: Temperature inside the cabin of a car in summer season gets very high in parking condition which is uncomfortable to driver as well as to passengers boarding in it. In this paper an investigation has been done for air-circulation and temperature distribution in compartment of a car with different inlet velocities considering an inlet vent in front and an outlet in rear of the car. It is observed that air circulation is more efficient in rear compartment than front compartment of the car with increase in inlet velocity of air. Temperature distribution gets better with increase in the inlet velocity and overall cabin temperature is reduced with providing vent in the cabin. Keywords: thermal comfort, CFD, passenger cabin.
