Two typical ways of air supply and air return's of air-conditioning room numerical simulation

The paper is based on the CFD software,the material is defined as humid air(mixture of water and vapor) in FLUENT,and the same air-conditioning room is simulated by same air supply condition but different ways of air supply and air return with k—e model,then velocity distributions,temperature distributions and pressure distributions of two ways of air supply and air return are obtained,by which the best way of air supply and air return is selected.
