Three-dimensional numerical simulation of a hybrid fresh air and recirculated air diffuser for decoupled ventilation strategy

For that paper, a new ventilation strategy is numerically simulated, this new approach consists in supplying fresh air directly by using high velocity circular air jet without mixing with recirculated air.Different angles of recirculated air diffuser blades, different lengths and directions of protruding fresh air jets are adopted along with different inlet velocities of fresh air to compare the effectiveness and efficiency of that new ventilation strategy numerically.
