为了研究冰晶的下落速度，用模型实验法测量了圆柱体和圆盘的阻力系数。测量了不同液体下落模型的末端速度，并由速度计算出阻力系数和雷诺数。本模型试验结果适用于雪晶下落速度的计算。因此，可以认为本实验的阻力系数适用于利用冰晶的质量或密度及其尺寸来计算冰晶的下落速度。
In order to study the falling velocity of ice crystals, the drag coefficients of circular cylinders and circular disks were measured by a model experimental method. The terminal velocities 0f falling models in various liquids were measured and the drag coefficient and Reynolds number were computed from the velocities. The result of the present model experiment was applicable to computation of the falling velocity of snow crystals. Therefore, it may be considered that the drag coefficient of the present experiment is applicable to computation of the falling velocity of ice crystals with using the mass or density and the dimension of them.
