势流近似或假设零涡度不一定需要进行无粘近似。 在大多数情况下,势流中粘度的影响可以忽略不计,也不重要。 然而,在 PI 概述的情况下,粘性效应可能会产生微妙但显着的后果。 Pi 开创了他所说的粘性势流的研究。这项工作对于毛细管塌陷附近的液体空化(物理学界正在积极研究的现象)、超空化和应力诱导空化以及声学效应等其他领域非常重要。
英文摘要
Potential flow approximation or assuming zero vorticity does not necessarily require making an inviscid approximation. In most cases, the effect of viscosity in potential flow is negligible and not important. However, in the cases outlined by the PI, the viscous effect may have subtle but significant consequences. The Pi has pioneered the investigation of what he refers to as the viscous potential flow.This work will be important in cavitation of liquids near capillary collapse (the phenomena under active investigation in the physics community), supercavitation and stress induced cavitation, and other areas such at acoustic effects.
