A numerical simulation model that predicts the thermal comfort in public transportation buses was developed. A precise approach based on the assembly of zonal and nodal models, coupled with CFD results obtained for stationary conditions, is used to simulate the thermal and air flow phenomena inside the passenger compartments. The model allows to determine the thermal (solar, passenger, and convective) loads of the bus and then to qualify the comfort level using the equivalent temperature. Simulations carried out show the influence of air distribution inside the bus on passenger’s thermal comfort.
