Blowing/suction effect on hydromagnetic heat transfer by mixed convection from an inclined continuously stretching surface with internal heat generation/absorption

The problem of steady, laminar, hydromagnetic heat transfer by mixed convection over a continuously stretching surface with power-law variation in the surface temperature or heat flux in the presence of internal heat generation/absorption effect is investigated. The surface velocity of the stretchin...

description The problem of steady, laminar, hydromagnetic heat transfer by mixed convection over a continuously stretching surface with power-law variation in the surface temperature or heat flux in the presence of internal heat generation/absorption effect is investigated. The surface velocity of the stretching surface was assumed to vary according to power-law. The surface is assumed to be permeable to allow for possible fluid wall blowing or suction. The governing non-similar equations are obtained by introducing a suitable transformation and are solved numerically. The obtained results are checked against previously published work on special cases of the problem and are found to be in excellent agreement. A parametric study is performed to illustrate the influence of the magnetic parameter, wall mass transfer coefficient, the coefficients of space-dependent and temperature-dependent internal heat generation/absorption, and the buoyancy force parameters on the fluid velocity and temperature profiles. Numerical data for the local skin-friction coefficient and the local Nusselt number have been tabulated for various parametric conditions.
