Magnetohydrodynamic flow for a non-Newtonian power-law fluid having a pressure gradient and fluid injection

Abstract

The nonlinear partial differential equation of motion for an incompressible, non-Newtonian power-law fluid flowing over flat plate under the influence of a magnetic field and a pressure gradient, and with or without fluid injection or ejection, is transformed to a nonlinear third-order ordinary differential equation by using a stream function and a similarity transformation.The necessary boundary conditions are developed for flow with and without fluid injection (or ejection), and a solution for four different power-law fluids, including a Newtonian fluid, is presented.The controlling equation includes, as special cases, the Falkner-Skan equation and the Blasius equation.

Steady MHD mixed convection flow of a viscoelastic fluid over a magnetized convectively heated vertical surface with Hall current and induced magnetic field effects

“…In his study, he considered two models, namely the Bingham plastic model and the power law model to study the dynamics of non‐Newtonian fluid flow within two parallel nonconducting surfaces. Subsequently, Sapunkov, 2 Djukic, 3 Cobble, 4 and Desai and Timol 5 analyzed the effect of external magnetic field on the flow of electrically conducting non‐Newtonian fluids. Thereafter, a series of investigations were performed by researchers to discuss the effect of external magnetic field on the flow characteristics of non‐Newtonian fluids.…”
