Unraveling the Thermo-Physical Properties of MHD Heat and Mass Transfer of Nano-Fluid Flow over a Nonlinear Permeable Stretching Sheet

Abstract

Investigating MHD Heat and mass transfer of nano-fluid over a permeable stretching sheet can lead to improved storage, handling and usage. This work therefore examined the significance of temperature-dependent viscosity and temperature-dependent thermal conductivity on MHD heat and mass transfer of nano-fluid over a nonlinear permeable stretching sheet. The governing partial differential equations describing the nanofluid flow are transformed and parameterized into a system of ordinary differential equations. The resulting mathematical model was solved numerically using the shooting technique with the fourth-order Runge-Kutta method. Graphical analysis is conducted to investigate the impact of certain fluid parameters on the momentum, thermal and concentration equations. The results from the graphs showed that temperature-dependent viscosity and temperature-dependent thermal conductivity have appreciable effects on the model.
