Drag on a fluid sphere embedded in a porous medium
Brinkman equation Modified Bessel functions Drag force
2010/9/26
The problem of the Stokes flow past a fluid sphere embedded in a porous medium is studied. The Brinkman equation for the flow outside the fluid sphere and the Stokes equation for inside the fluid sphe...
Two dimensional curved disks on a sphere: the evolution of kinetic energy
curved space kinetic energy
2010/9/27
We put disks on a sphere between two parallels of this sphere. The disks have the curvature of the sphere and interact via a simplified Hertz law. We analyze the behavior of the total kinetic energy o...
