Convective Conditions on 3D Magnetohydrodynamic (MHD) Non-Newtonian Nanofluid Flow with Nonlinear Thermal Radiation and Heat Absorption: A Numerical Analysis

Abstract

Three-dimensional flow of non-Newtonian nanofluid with nonlinear thermal radiation and heat absorption is established numerical analysis. We are taken that, the nonlinear thermal radiation and heat absorption on porous stretching sheet. Moreover, we have to consider the Magnetohydrodynamic and convective conditions within the fluid motion on stretching surface. The similarity variables are implemented to translate the nonlinear PDE into a set of coupled system of ODE which are solved numerically via RKF (“Runge-Kutta-Fehlberg”) 4th order based on shooting procedure. We obtained the dimensionless parameters on velocity, temperature and concentration profiles and as well as skin friction coefficient, Nusselt number and Sherwood numbers are discussed through graphs. In this study, we found interesting results, that is the non-Newtonian fluids is most significant on velocity, temperature, and heat transfer rate is high significant in non-newtonian case when compared with nanofluid case with various statistical values of Pr (“Prandtl number”), θw (“Temperature ratio parameter”) and Nt (“Thermophoresis parameter”), respectively.

Entropy and energy transfer analysis of a Maxwell thin‐film fluid over an inclined surface with viscous dissipation effect

“…Sudarmozhi et al [10] proposed a chemically reactive Maxwell fluid flow with a magnetic effect through a vertically-slanted permeable plate, and the heat production is analyzed by using the RK45 method. There are many numbers of researches made in different non-Newtonian fluids [11][12][13][14][15][16][17][18] to study the behavior and energy transfer rate.…”
