CFD Analysis of Airflow inside a Car Compartment

Abstract

In the present study a finite volume based computational procedure is used to investigate the air flow analysis inside a car compartment. The compartment used for flow and heat diffusion analysis has been bounded by convective boundary conditions for the bottom wall, the top surface and the front and rear wind shields open to heat flux radiating from the sun, the air entering the car compartment with certain velocity and temperature through the inlet vent, the outlet vent to be at gauge pressure, humans and seats are considered to be a solid part and thus considering no heat radiating from humans. The flow is assumed to be turbulent and the air to be incompressible. The analysis has been carried out for 2D car compartment.
