【摘要】 用Ｗ．Ｋ．Ｂ法对大宽高比方形通道中气溶胶粒子对流扩散方程作了详细求解．利用所得结果推断了粒子在沿气流流动方向壁面上的沉积特性，并对两类通道中的气胶粒子沉积特征进行了比较．更多还原

【Abstract】 The convective diffusion equation of aerosol particles in ducts with large width to height ratio is solved by employing the method of W.K.B approximation. The characteristics of diffusional deposition of particles on the walls are presented, and the deposition features of aerosolos in ducts and cylindrical tubes are also brought into comparison.更多还原
