The numerical simulation of indoor air velocity distribution and temperature distribution in steady-state two-dimensional air-conditioned vehicle was carried out. The calculation grid and SIMPLEST numerical calculation method were adopted. The influence of natural convection on air flow field was considered. The turbulence model adopted K -ε model to solve the problem of solid-gas coupled heat transfer using the whole solution method. The change of velocity field and temperature field of air-conditioned indoor air flow under certain inlet Reynolds number and air supply angles were calculated. The calculation results of this paper laid the foundation for the optimization design of indoor air distribution in air-conditioned vehicles and the research on air intake comfort control of air-conditioned cabs.
