| Popis: | The present analysis is made to envision the characteristics of thermal and solutal stratification on magneto-hydrodynamic mixed convection boundary layer stagnation point flow of non-Newtonian fluid by way of an inclined cylindrical stretching surface. Flow exploration is manifested with heat generation process. The magnitude of temperature and concentration nearby an inclined cylindrical surface is supposed to be higher in strength as compared to the ambient fluid. A suitable similarity transformation is applied to transform the flow conducting equations (mathematically modelled) into system of coupled non-linear ordinary differential equations. The numerical computations are made for these subsequent coupled equations with the source of shooting scheme charted with fifth order Runge-Kutta algorithm. A logarithmic way of study is executed to inspect the impact of various pertinent flow controlling parameters on the dimensionless velocity, temperature and concentration distributions. Further, straight line and parabolic curve fitting is presented for skin friction coefficient, heat and mass transfer rate. It seems to be first step in this direction and will serve as a helping source for the preceding studies.
