Abstract


The unsteady MHD mixed convective laminar boundary layer ?ow of an incompressible viscous ?uid over continuously stretching permeable surface in the presence of thermal radiation, heat generation and chemical reaction is studied. The unsteadiness in the momentum, temperature and concentration ?elds is because of the time-dependent stretching velocity and surface temperature and concentration. Similarity transformations are used to convert the governing time dependent boundary layer equations into to a system of nonlinear ordinary coupled differential equations containing Magnetic parameter, Thermal convective parameter, Mass convective parameter, Suction parameter, Radiation parameter, Eckert number, Prandtl number, Heat source parameter, Chemical reaction parameter, Schmidt number, Soret number and Unsteadiness parameter. TheNactsheim-Swigert shooting technique together with Runge-Kutta six order iteration schemes has been used for numerical procedure. Comparisons with previously published work are performed and are found to be in excellent agreement. The effects on the velocity, temperature and concentration distributions as well as skin-friction coefficients, Nusselt number and Sherwood number of the various important parameters are discussed graphically.
