Numerical Simulation and Experimental Research on Flow Field of Swirling Cold Air Diffuser

Experimental and numerical research was carried out on swirling cold air diffuser. In experimental research, following the cold air distribution requirements, cold air distribution experiment table was constructed for testing specimen of swirling cold air diffuser. In numerical research, Fluent software was applied to analog calculate air distribution of air conditioning room flow field for this air diffuser. The obtained result was compared with the experimental result, both were in good agreement. It indicated that temperature field and velocity field is uniform in swirling cold air diffuser room, which supplied theoretical and experimental basis for actual application of this air diffuser.
