摘要
首先探讨了线性化后的稀疏颗粒非恒定运动方程的数理性质，然后采用积分变换方法对该方程进行解析，得到了颗粒速度与流体速度间的相互关系．在此基础上分析了颗粒物理性质对其运动特性的影响，并通过计算典型流场中颗粒的运动，进一步定量地显示出颗粒运动随流场结构、颗粒密度和粒径变化的规律．
The mathematical property of the linearized dilute particles' transient motion equation has been discussed before the equation is analyzed with integral transform methods, with relationships of particles velocity to fluid velocity being obtained. Based upon the above results, the effects of particles' physical property on its motion are explored, and particles' motions are calculated in some typical flow fields. It is quantitatively showed by calculations that particles motions vary with flow structure, particles' diameters and densities.
