Effects Of Permeability And Radiation On The Stability Of Couette Flow In A Porous Medium
Ngiangia, Alalibo T. & Nduka, Wonu
Abstract
A study on the effects of permeability and radiation on the stability of couette flow in a porous
medium was carried out. The pressure differential of the equation of motion is kept constant in the Navier-Stokes
equation and solution developed by the method of undetermined coefficients.It was observed that radiation and
permeability has, independently destabilizing effect on the stability of couette flow. At high wave numbers (a ≤
10) and Reynolds number (Re ≥ 2500), instability sets in but at wave numbers (a ≤ 5) stability was not affected.
However, within the same range of values, radiation effect was prominent.
