Effects of Temperature-Dependent Viscosity on Thermally Developing Forced Convection through a Porous Medium

ABSTRACT

Thermally developing laminar flows in ducts with temperature-dependent viscosity variation are analyzed, where the Arrhenius model for the variation of the viscosity with the temperature is made. The Darcy flow model is assumed. The case of isoflux boundaries is treated. For a fluid whose viscosity decreases with temperature, it is found that the effect of the variation is to reduce/increase the Nusselt number for cooled/heated walls.
