Experimental study was made on promotion and control of turbulent mixing of hot and cold airflows in a T-junction, which simulated an HVAC unit for automobile A/C system. Two kinds of delta wings were used as a mixing promoter, and the influence of their attack of angles on the thermal mixing and flow field were examined in detail. It was found that the thermal mixing is promoted by longitudinal vortices and strong turbulence produced by the delta wings, and the degree of mixing promotion can be controlled by changing the angle of attack of the wings.
