Oscillations of Second Order Fluids near a Sphere

Abstract

The high frequency oscillations of second-order fluids near a fixed sphere have been considered. The peculiarity of the second-order fluid is that the magnitude of the steady secondary streaming at large distance from the sphere depends upon all the material constants, while for a Newtonian fluid, this is not so. The drag on the sphere has been calculated for various values of the non-dimensional parameters formed out of the material constants and the flow parameters. The outer motion is pushed away from the sphere with increase in the non-dimensional parameters.
