Viscous dissipation effect on the flow through a horizontal porous channel with temperature dependent viscosity

This work investigates the flow of fluid through a horizontal channel filled with a porous media with a temperature dependent viscosity. The influence of Darcy number on the velocity and temperature was thoroughly investigated. It is observed that high Darcy number leads to a higher velocity and that velocity is parabolic while reversal flow takes place at low Darcy number, while at very low Darcy number, oscillation and instabilities of flow is observed. It is also observed that as the brinkman number increases the temperature profile increases.Journal of the Nigerian Association of Mathematical Physics, Volume 15 (November, 2009), pp 133 – 13
