In this article, the steady-state flow of a Hagen-Poiseuille model in a circular pipe is considered and entropy generation due to fluid friction and heat transfer is examined. Because of variation in fluid viscosity, the entropy generation in the flow varies. In this model, Arrhenius law is applied

Abstract
The stability of convective motion of a fluid driven by volumetric heat sources and applied pressure gradient is investigated. The viscosity of the fluid is assumed to depend linearly on temperature. The sufficient conditions for the existence of such a flow are obtained based on the energy inequalities. Copyright Β© 2007 John Wiley & Sons, Ltd.

We present a new strategy to accelerate the convergence rate of a high-accuracy multigrid method for the numerical solution of the convection-diffusion equation at the high Reynolds number limit. We propose a scaled residual injection operator with a scaling factor proportional to the magnitude of t
