Abstract
In this article the influence of thermal radiation on magnetohydrodynamic (MHD) flow of Cu-water nanofluid past a wedge in the occurrence of viscous-Ohmic dissipation and chemical reaction has been analyzed. The non-linearity numerical approach called RKF of the 4–5th order have been used with a shooting technique to find the results of velocity, temperature and concentration field for several points of employing parameters. The skin friction coefficient, Nusselt number and Sherwood number are examined in detail and the results are illustrated by figures and tables. The outcomes declared that the concentration boundary layer width diminishes with an increase in the values of the chemical reaction parameter and velocity profiles increase with increase in the magnetic field parameter.
