Experimental Study of Natural Ventilation Driven by Wind Pressure Based on PIV System
风压作用下房屋自然通风的PIV实验研究

In order to realize the flow structure and improve the effect of natural ventilation in a house,wind tunnel house model experiment of cross natural ventilation driven by wind pressure through large openings was carried out and its results are presented in this paper.Firstly,the surface pressure distribution on the model was measured.Thus the distribution of wind pressure coefficient on the house model surface was obtained,which formed the basis for selecting appropriate opening position.Then,in order to und...
