The effect of power law body forces on a thermallydriven flow between concentric rotating spheres
Abstract
A numerical study is conducted to determine the effect of powerlaw body forces on a thermallydriven axisymmetric flow field confined between concentric corotating spheres. This study is motivated by Spacelab geophysical fluidflow experiments, which use an electrostatic force on a dielectric fluid to simulate gravity; this force exhibits a (1/r)sup 5 distribution. Meridional velocity is found to increase when the electrostatic body force is imposed, relative to when the body force is uniform. Correlation among flow fields with uniform, inversesquare, and inversequintic force fields is obtained using a modified Grashof number.
