Abstract

A numerical study of a three-dimensional, turbulent, recirculating flow within a passenger car cabin is presented.
The study is based on the solution of the partial differential equations representing conservation of mass, momentum,
temperature, turbulence energy and its dissipation rate in finite volume form. Different parameters are considered to
illustrate their influences on the flow filed and temperature distribution inside car cabin. These parameters include number
and location inside car cabin, different air temperatures at the inlets and outlet, different air velocities at the inlets and outlet.
This paper focuses on the numerical study of the temperature field and air flow inside a passenger’s cabin using
computational fluid dynamics (CFD) method.
Generally, the results indicate some of negative effects such as development of zones of high air circulation. Also it is fou nd
that the location of inlets inside car cabin play an important role in determining car air con ditioning system efficiency.
Moreover, the air temperature and velocity at inlets play an important role in determining cabin climate. The results are
used to enhance the understanding of the airflow fields within a road vehicle passenger cabin.
