Effect of radiation and chemical reaction on an unsteady Walter’s-B viscoelastic MHD flow past a vertical porous plate. (English) Zbl 1367.76066

Summary: This paper investigates study of unsteady Walter’s-B viscoelastic MHD (magnetohydrodynamics) flow past a vertical porous plate embedded in porous medium with the effects of radiation and chemical reaction. Dimensionless partial differential equations of governing equations of flow are solved numerically using Crank-Nicolson finite difference method. Velocity, Temperature and Concentration profiles are discussed through graphs for different values of parameters. Skin-friction coefficients, Nusselt number and Sherwood number are discussed through tables for different values of parameters.
