摘要
在环境风洞中模拟大气边界层是大气污染对流扩散试验研究的前提.根据环境风洞污染扩散试验的特点,通过试验调整大气边界层模拟装置,实现了在环境风洞中模拟部分大气边界层,并通过湍流结构确定了模拟比尺.当大气边界层得到正确模拟时,在环境风洞中模拟污染扩散和在大气边界层中的实际情形相似.
Simulating atmospheric boundary layer in environmental wind tunnel is the precondition of the research on the convection and diffusion of atmospheric pollutants.Based on the characteristics of the diffusion of pollutants in environmental wind tunnel,it should satisfactorily adjust simulation setup by experiment to model more accurately the partial atmospheric boundary layer in environmental wind tunnel and to determine the simulation scale in accordance with turbulence structure.When atmospheric boundary layer is simulated correctly,the diffusion of pollutants under different model scales in environmental wind tunnel is similar to that in atmospheric boundary layer.
