Study on a novel ventilation mode based on attached air curtain in non-isothermal condition

By comparative analysis of traditional airflow patterns used in HVAC system, presents a novel ventilation mode based on attached air curtain. Using full scale visualization experiment and CFD numerical simulation, studies the velocity and temperature field distribution of this mode, under different supply air velocities, temperatures and slot locations in the non-isothermal condition. Meanwhile, obtains the formulation of maximum jet velocity decay. The results show the ventilation mode can create comfortable environment in occupied zone, with higher ventilation efficiency.
