Effect of mass transfer and radiation on mixed convection boundary layer flow over a permeable vertical cylinder with surface heat flux and mass flux

Abstract In this study, the effects of mass transfer and radiation on mixed convection boundary layer flow over a permeable vertical cylinder with surface heat flux and mass flux have been investigated. The free stream velocity and the surface heat flux are assumed to vary linearly with the distance from the leading edge. The governing system of partial differential equations is first transformed into a system of ordinary differential equations, and the transformed equations are solved numerically for both assisting and opposing flow regimes using a fourth-order Runge-Kutta scheme with the shooting method. Velocity, temperature, and concentration distributions were numerically discussed and presented in the graphs. Skin-friction coefficient, Nusselt number, and Sherwood number on the cylinder were derived and discussed numerically. Their numerical values for various values of physical parameters were presented in the tables. The results obtained are comparing with the published results for various authors, and it is found to be a good agreement.
