| 摘 要： | 将圆柱状粒子和圆球粒子建立等效关系,由等效面积法得到了作用在圆柱状粒子上的阻力,然后通过有限体积法对圆柱状粒子的阻力进行了数值求解,经比较发现,在层流状态时由等效面积法得到的圆柱状粒子的阻力要乘上一个1．5—2的常系数．

| Abstract: | The equivalent relation between the spherical and cylindrical particles was built, and the method of equivalent surface area was used to calculate the drag exerted on the cylindrical particle. Then the finite-volume method was applied to obtain the drag numerically. It is found that the drag obtained by the numerical method differs from that obtained by the equivalent surface area method by a factor of 1.5-2. |
