We can use Principe of frame of reference and let the flow enter and exsit and keep the bus stationary. The bus can be resolved or you use just the contour of the walls (depending on the scope) and you input temperature or heat flux at the heated surface of the bus. The region of interest better to assign it a sort of dedicated cell zone where you can input source terms to depict the momentum added due to fan. We have a basic tutorial on that on the Ansys Learning Hub.
