补充资料:气体动力学当量直径(aerodynamic equivalent diameter)
分子式:
CAS号:

性质:又称气体动力学当量直径(aerodynamic equivalent diameter)。表述粒于运动的一种假想粒径(粒子直径)。定义为:单位密度(ρ0=1g/cm3)的球体,在静止空气中做低雷诺数运动时,达到与实际粒子相同的最终沉降速度(Vs)时的直径。也就是将实际的颗粒粒径换成具有相同空气动力学特性的等效直径(或等当量直径)。由于通常难以测得实际颗粒的粒径和密度,而空气动力学直径可直接由动力学的方法测量求得;这样可使具有不同形状、密度、光学与电学性质的颗粒粒径有了统一的量度。由大气颗粒物的实际粒径(d),可按下式求算其空气动力学的直径(da);或反求算之。            式中Ca为采用da时所用的cunningham滑失修正系数,C为cunningham滑失系数,ρp为实际颗粒的密度。作为一级近似,可令C=Ca,就可简易地进行两种直径的互算。
