Abstract
Impact of viscous dissipation and induced magnetic field in Brinkmann- Forchheimer extended Darcy flow of MHD mixed convectionsin a vertical microporous channel is investigated. Three different viscous dissipation models along with three different wall ambient temperature difference ratios are analysed. Projected results evidently indicate that the kind of viscous dissipation model has a notable impact on velocity distribution, induced magnetic field, current density, skin friction, and Nusselt number. It is found that an increase in Brinkman number increases velocity in the channel for distinct values of wall ambient temperatures difference ratios. Due to the domination of convection, an increase in Darcy number increases skin friction. The effect of induced current density on Darcy number, Brinkmann number, and inertial parameters are also discussed. The CFD data is used to train the built ANN model for predicting the heat transfer characteristics in the considered channel with 98.96% accuracy.
