MHD Stagnation Point Flow and Heat Transfer of a Nanofluid Over a Stretching Sheet Fixed in Porous Medium with Effect of Thermal Radiation, Joule Heating and Heat Source/Sink

Abstract

The goal of this research is to see how thermal radiation, joule heating, and heat Source/Sink affect two-dimensional nanofluid stagnation point flow above a stretching sheet fixed in a spongy medium. This research accounts for the magnetic field, and the nonlinear Rosseland approximation is used to calculate heat radiation. The governing equations are converted into a system via
similarity transformations in joined nonlinear ordinary differential equations, which are solved numerically using the Runge-Kutta fourth order approach with shooting technique. The numerical results reveal that this method has excellent correctness, good convergence with minimal computational cost, and a lot of promise. The velocity and temperature are also found to increase as
a function of the radiation parameter, Eckert number, Brownian motion parameter, Thermophoresis parameter, Biot Number, and thermal buoyancy parameter, as well as the reverse effect in Prandtl numeral. The skin friction, local Nusselt number, and local Sherwood number are increasing functions of the ratio of free stream velocity to stretching sheet velocity parameter, Biot number, Brownian motion parameter, and thermophoresis parameter, with the reverse effect in magnetic parameter, Prandtl number, and permeability parameter.
