柯氏力引起的流体“挤压”现象

本文从虚位移原理出发,计算了流体质点组成的质点系。在柯氏力作用下,流体的形态将因“挤压”现象而发生改变。对气体而言,由于“挤压”,将会导致气体密度分布的不均匀,造成沿气体流动方向两侧产生压力差。这种“挤压”现象在精确求解气团运动压力分布时,应予考虑。

Crowding in the fluid due to the Coriolis force

In this paper, based on the principle of virtual displacement, the changes in form of the particle system composing the fluid are calculated that leads to the "crowding" under the action of the Coriolis force. For a gas, the "crowding" will result in an imhomogeneous distribution of density, thus causing a pressure difference on both sides in the direction of its motion. Such "crowding" can serve as.a reference in finding the accurate solusion of the pressure distribution of air masses.
