Abstract
A two-dimensional steady flow of an electrically conducting, viscous incompressible nanofluid past a continuously moving surface is considered in the presence of uniform transverse magnetic field with chemical reaction. A mathematical governing model has developed for the momentum, temperature and concentration boundary layer. Similarity transformations using to modify the boundary layer equations. Whereas this prominent transformations are used to transform the principal nonlinear boundary layer equations for momentum, thermal energy and concentration to a system of nonlinear ordinary coupled differential equations with fitting boundary conditions. The coupled differential equations are numerically simulated using the famous Nactsheim-Swigert shooting technique together with Runge-Kutta six order iteration schemes. Pertinent results with respect to embedded parameters are displayed graphically for the velocity, temperature and concentration profiles and were discussed quantitatively. Skin-friction, Heat transfer rate (Nusselt number) and mass transfer rate (Sherwood number) are illustrated for the various important parameters entering into the problem separately are discussed with the help of graphs. Finally for the accuracy of the present results a comparison with previously published research work are accomplished and proven an excellent agreement.
