New ventilation schemes of car cabin evaluated by CFD simulations

Computational fluid dynamics (CFD) was used to investigate new ways of air conditioning a car cabin during summer conditions. Three different schemes ventilation were considered: classical mixing (dashboard vents), large-area ceiling vents, and underfloor vents delivering under the seats. The Star-CCM+ carry out unsteady RANS simulations resulting temperature velocity fields compared. Furthermore, draft risk age evaluated for each scheme. For cabin, had best results.
