Numerical Simulation of Air Diffusion in Highway Toll Booths
Numerical simulation of air diffusion characteristics in toll booths under different air supply outlet posi-tions and air supply parameters is carried out by using the method of computational fluid dynamics and finite ele-ment software.The simulation results of velocity field calculation show that the influence range of the jet is expand-ed with the increase of air supply velocity,and the airflow distribution is more uniform.In the case that the air sup-ply outlet is facing the human body,the 1.5 m high air supply outlet is better than that of 1.3 m high.The ar-rangement of the air supply outlet on the east wall will lead to a faster air renewal rate,which will not be sufficiently diffused.It is better to have the air supply on the north wall than on the east,south or top wall.
