半无限区域中的Stokes方程:Lamb解的推广及其在Marangoni流中的应用

Stokes equation in a semi-infinite region: generalization of Lamb solution and applications to Marangoni flows

G. Koleski, T. Bickel

摘要:

本文研究牛顿流体在半球形区域内的蠕动流动。在球面或近似球面的区域中,Stokes方程的解可以表示为一系列球谐函数。然而,原来的兰姆解决方案是不完整的,当流动被限制在一个半无限的空间。半球形几何的一般解决方案,然后明确地构建。作为应用,我们讨论了由于在液-气界面的局部源的Marangoni流的解决方案。

英文摘要:

We consider the creeping flow of a Newtonian fluid in a hemispherical region. In a domain with spherical, or nearly spherical, geometry, the solution of Stokes equation can be expressed as a series of spherical harmonics. However, the original Lamb solution is not complete when the flow is restricted to a semi-infinite space. The general solution in hemispherical geometry is then constructed explicitly. As an application, we discuss the solutions of Marangoni flows due to a local source at the liquid-air interface.
