An experimental study was made on the promotion and control of turbulent mixing of hot and cold airflows in a T-junction that simulated an HVAC unit for automobile A/C system. Delta wings were attached on the branch wall, and their optimum specification was determined based on the mixedness. The thermal mixing was promoted most effectively with a specification of N=9 and h/B=0.4, and the degree of the mixing could be controlled by changing the angle of attack of the wings. The dynamic range of the mixedness with the present wings was wider than that obtained when the delta wings were attached on the main-channel wall.
