Effects of temperature-dependent viscosity in channels with porous walls
The influence of temperature-dependent viscosity on the flow along a channel with porous walls at different temperatures was analyzed. Numerical schemes were developed to solve the Navier-Stokes equation and the energy equation, coupled through the dependence of viscosity on temperature. Bifurcation...
