Entropy Generation in Poiseuille Flow through a Channel Partially Filled with a Porous Material

Abstra t. In the present paper, a theoreti al analysis of entropy generation due to fully developed ow and heat transfer through a parallel plate hannel partially lled with a porous medium under the e e t of transverse magneti eld and radiation is presented. Both horizontal plates of the hannel are kept at onstant and equal temperature. An exa t solution of governing equation for both porous an...

Entropy generation analysis of MHD forced convective flow through a horizontal porous channel

Entropy generation due to viscous incompressible MHD forced convective dissipative fluid flow through a horizontal channel of finite depth in the existence of an inclined magnetic field and heat source effect has been examined. The governing non-linear partial differential equations for momentum, energy and entropy generation are derived and solved by using the analytical method. In addition; t...

Magnetic field effects on entropy generation in heat and mass transfer in porous cavity

The entropy generation for natural convection heat and mass transfer in a two dimensional porous cavity subjected to a magnetic field is selected for numerical investigation. The Darcy model is used in the mathematical formulation of the fluid flow in porous media. The mathematical model is derived in dimensionless form and the governing equations are solved using the finite volume method. The ...

Entropy Generation in a Couple Stress Fluid Flow Through a Vertical Channel Filled with Saturated Porous Media

The present work investigates numerically the inherent irreversibility in a steady flow of a couple stress fluid through a vertical channel packed with saturated porous substances. The First and Second Laws of Thermodynamics are applied to analyze the problem. The nonlinear governing equations in Cartesian coordinates are obtained and solved numerically using shooting methods together with a Ru...
