Szukana fraza: [Abstract = "The effects of thermal radiation and mass transfer on an unsteady hydromagnetic boundary layer mixed convection \?ow along a vertical porous stretching surface with heat generation are studied. The \?uid is assumed to be viscous and incompressible. The governing partial differential equations are transformed into a system of ordinary differential equations using similarity variables. Numerical solutions of these equations are obtained by using the Runge\-Kutta fourth order method along with the shooting technique. Velocity, temperature, concentration, the skin\-friction coefficient, Nusselt number and Sherwood number for variations in the governing thermo physical parameters are computed, analyzed and discussed."]
