Abstract

This paper deals with a laminar swirling flow of a viscous fluid over a stretchable rotating disk. The classical flow over a solid disk is known as the Kármán flow problem. For the first time in the literature, the combined effects of both the Coriolis force and radial stretching on the stability of the Kármán swirling flow has been carried out. The numerical investigation has been performed by using the Chebyshev spectral method. It is discovered that surface stretching produces a destabilising effect on the Kármán flow.

科里奥利力对可拉伸旋转圆盘上KÁRMÁN旋流的对流不稳定性的影响

摘要

本文讨论了粘性流体在可拉伸转盘上的层流旋流。固态磁盘上的经典流称为卡尔曼流问题。在文献中,科里奥利力和径向拉伸对卡尔曼旋流稳定性的综合影响是第一次。通过使用切比雪夫光谱方法进行了数值研究。发现表面拉伸对卡尔曼流产生破坏作用。
