| Abstract: | The present paper introduces the boundary layer wind tunnel and its measurement and control systems of Sando university.The wind tunnel is mainly used for experimental research of wind resistance and wind circumference on building.In order to simulate boundary layer in atmosphere,the length of first test section is longer than usual one,the models are put into the rear part.The height of each ceiling plate is adjustable,for reducing static pressure gradient in axis direction.The maximum flow velocity is lower than that in aeronautical wind tunnel.It is equipped with the electronically scan pressure measurement system and high frequency base balance both used separately for the measurement of pressure and forces on building The flow field calibration show that the aerodynamic performance of the wind tunnel has satisfied the requirements of the contract. |
