CFD Simulation for the Improvement of Thermal Comfort in Cars

The results are presented of an investigation into aspects of thermal comfort inside cars using the Computational Fluid Dynamics (CFD) software Fluent from Ansys. A global thermal comfort index was developed based on four indices - the thermal equilibrium of the human body, discomfort caused by draughts, the vertical temperature gradient and the horizontal temperature gradient. The numerical procedure is outlined and the various choices of approach made are explained. The physical tests were carried out in a wind tunnel under 'warming' and 'cooling' conditions using a Ferrari 599. The correlation between experimental and numerical data was found to be satisfactory in warming conditions but less so in cooling conditions. The results and implications for design changes are considered. The problems experienced in determining some of the local indices are noted and suggestions made for further research.
