Electromagnetic steady motion of Casson fluid with heat and mass transfer through porous medium past a shrinking surface

The motion of non-Newtonian fluid with heat and mass transfer through porous medium past a shrinking plate is discussed. obeys Casson model, generation, viscous dissipation, thermal diffusion, chemical reaction are taken in our considered. modulated mathematically by system non-linear PDE which describe the continuity, momentum, heat, equations. These equations transformed into ODE using suitable transformations. solved numerically MATHEMATICA package. numerical distributions velocity, temperature, concentration obtained as functions physical parameters problem. Moreover, effects these on solutions discussed illustrated graphically some figures. It clear that play an important role to control motion. found velocity deceases increasing electric parameter while it increases magnetic Hartman increases, results good agreement situation. Also, temperature decreases Prandtl number Eckert respectively. At least both Soret Schimdt numbers.
