摘要

提出了一个物理数学模型，用于评估离心力对大型过冷液滴与在同轴气流中旋转的球体碰撞后形成的针状冰的特征尺寸的影响。模型考虑了液滴与表面碰撞时因飞溅造成的质量损失。通过对模型进行数值计算，可以研究表面特性对结冰过程的影响，特别是可以估算离心力导致的无冰表面积。

Physicomathematical Model of Icing of the Rotating Sphere in a Coaxial Supercooled Gas-Drop Flow

A physico-mathematical model is proposed for assessing the effect of centrifugal force on the characteristic dimensions of needle-shaped ice formed as a result of the collision of a large supercooled drop with a sphere rotating in a coaxial air flow. The mass loss of droplets upon collision with the surface due to splashing is taken into account. The numerical implementation of the model makes it possible to study the effect of surface properties on the icing process and, in particular, to estimate the ice-free surface area due to centrifugal force.
