Heat and Mass Transfer by Hydromagntic Mixed Convection Flow along a Vertical Cylinder Embedded in a Non-Darcy Porous Medium with Heat Source

The problem of coupled heat and mass transfer by steady mixed convection flow of an incompressible, viscous and electrically conducting fluid along a vertical cylinder embedded in a non-Darcy porous medium with heat generation will be studied. The problem will be analyzed for the case of variable surface temperature and concentration. The entire region of the mixed convection is involved. The mixed convection parameter varies from pure natural convection to pure forced convection. The partial differential equations will be transformed into the non-similar boundary layer equations, which can be solved numerically by the finite difference method. From the present study, it can be concluded that rise in curvature and buoyancy ratio factors lead to higher heat and mass transfer. Heat and mass transfer drop as the inertia and square of Hartmann number rises. As Lewis number increases, Nussel number drops while Sherwood number rises. Increasing the heat generation parameter leads to lower Nusselt number. Sherwood number doesn't affect when increasing the heat generation parameter.
