Wind tunnel tests of wind pressure on regularly aligned buildings

Abstract

Model experiments are carried out in order to make the characteristics of wind pressure on groups of buildings clear. The wind pressure is thought to be a natural ventilation force and the model buildings are assumed to be apartment buildings. The approaching flow of the wind tunnel tests simulates the wind over a built-up area. The main parameter of the layout of buildings is the building volume ratio. A staggered grid layout is compared with a normal grid layout. The effect of the wind direction is also examined. The results of the experiments are presented as the wind pressure coefficient difference between windward and leeward. The relations between the average wind pressure coefficient in a model and various layouts of buildings are mainly discussed. The distributions of the wind pressure coefficient in model buildings are also presented in this paper.
