MHD convective stagnation flow of nanofluid over a shrinking surface with thermal radiation, heat generation and chemical reaction

摘要

The present study numerically investigates the phenomena of the steady two-dimensional magnetohydrodynamic(MHD) stagnation-point and heat-mass transfer flow of a nanofluid past a shrinking sheet with the influence of thermal radiation, heat generation and chemical reaction. The effect of Brownian motion and thermophoresis are well-thought-out instantaneously. A similarity solution is presented which depends on the magnetic parameter (M), Grash of number (G), modified Grash of number (G), heat generation parameter (Q), radiation parameter (R), Brownian motion number (N), thermophoresis number (N), Prandtl number (P), Lewis number (L), Chemical reaction parameter (γ) and the ratio of the rate constants of the shrinking velocity to the free stream velocity (α). A shooting technique is employed to solve this similarity model numerically. The results of the present analysis is going to observe the velocity, temperature, concentration, the wall shear stress, the Nusselt number and the Sherwood number at the different situation and dependency of different parameters. A comparative study is also being shown between the previously published results and the present results for the accuracy and interesting findings of the present research.
