Hall current and Ion Slip effects on three-dimensional radiating Eyring-Powell fluid flow past a stretching sheet with Prandtl number and Magnetic field

Resumo

This work determines the effect of ion slip and Hall current on the three-dimensional Eyring-Powell fluid flow across a stretched sheet by considering the Prandtl number, magnetic fields, and temperature radiation.  With the use of MATLAB's "bvp4c" solution, the regulating equations may be reduced to a system of nonlinear ordinary differential equations.  Main and secondary velocity patterns, temperature distributions, skin-friction coefficients, and Nusselt number are examined using a variety of non-numerical parameters.  To validate the numerical technique, previous research was compared to it. Results demonstrate strong agreement, indicating the analysis was accurate and dependable.  One noticeable effect of the magnetic field parameter is a much smaller velocity boundary layer.  When the Eyring-Powell factors modify the velocity, the observed findings are seen to be incorrect.  In general, a lower Prandtl-Biot number indicates decreasing temperatures and a greater thermophoretic while Brownian motion coefficient indicates increasing temperatures.  We examine the three-dimensional effects of heat radiation, Hall current, and ion slips on the flow of a Casson nanofluid using computational approaches for a stretched sheet.  A solution to the governing equations is found using MATLAB’s bvp4c function.  In our knowledge, no previous studies have investigated the combination of physical effects with modeling techniques in this way.
