TLDR
In this paper, a combination of Galerkin's method and variational principle was used for the approximate solution of creeping flow of power-law fluid over a Newtonian fluid sphere.Abstract:
A technique which is a combination of Galerkin's method and variational principle was developed and used for the approximate solution of creeping flow of power-law fluid over a Newtonian fluid sphere. The stream functions (both internal and external) and drag coefficient are expressed in terms of three parameters: the flow behavior index of the power law fluid, the external Reynolds number, and a viscosity ratio parameter . Comparisons with existing experimental data are also given.read more

Diapiric ascent of magmas through power law crust and mantle
TL;DR: In this article, the ascent velocity of diapirs is calculated through an equation with the form of the Hadamard-Rybczynski equation for the rise of spheres through Newtonian ambient fluids.

Flow of inelastic and viscoelastic fluids past a sphere
TL;DR: In this article, an approximate closed form analytical solution has been obtained for the motion of a solid sphere in powerlaw fluids and this solution was verified experimentally using boundary layer theory; the results were used to separate form and skin friction.
