Effects of chemical reaction, heat and mass transfer on non-linear MHD laminar boundry-layer flow over a wedge with suction or injection

摘要

An approximate numerical solution for the steady MHD laminar boundary-layer flow over a wall of the wedge with suction or injection in the presence of species concentration and mass diffusion has been obtained by solving he governing equations using R.K.Gill method. The fluid is assumed to be viscous and electrically conducting Boussinesq fluid. A magnetic fild is ap- plied transversely to the direction of the flow. Numerical calculations up to third level of trunca- tion are carried out for different values of dimensionless parameters and an analysis of the results obtained shows that the flow field is influenced appreciably by the magnetic field, chemical reaction and suction or injection at the wall of the wedge.
