Abstract Present work concerns numerical solutions of hydromagnetic slip flow of Casson fluid under the influence of chemical reaction and convective boundary conditions. The flow is generated due to power law stretching sheet placed inside a porous medium. The nonlinear governing equations are transformed into nonlinear ordinary differential equations via suitable transformations. The transformed equations are then solved numerically using Keller-box method and graphical results are produced through MATLAB software. The influence of pertinent parameters on velocity, temperature, concentration profiles, as well as wall shear stress, heat and mass transfer rates is performed and examined qualitatively. The obtained numerical results are compared with previous work and presented in tabular form.
