Exploring the features of Von-Karman flow of tangent hyperbolic fluid over a radially stretching disk subject to heating due to porous media and viscous heating

Abstract

The fluid flow over rotating disk has various applications in the field of medical sciences, science and engineering i.e. medical equipment, gas turbine rotors, rheometers, oceanic circulation, and computer storage devices. Keeping this in mind, the task of this study is to observe the tangent hyperbolic fluid flow behaviors through a rotating disk in the presence of Ohmic heating, thermal radiation, viscous dissipation and heating due to porous media. The bvp4c numerical method is applied to solve the transformed governing equations. The impact of acting parameters i.e. magnetic field, porosity parameter, radiation, Weissenberg number and Eckert number on the velocities (radial, azimuthal and axial) and temperature distributions are revealed through graphs for the case of Newtonian and non-Newtonian fluids by considering no rotation ([Formula: see text]) and rotation parameter ([Formula: see text]). From the results, it is noticed that the resistivity offered by the increasing porosity increases the rate of heat transfer in magnitude for the case of no rotation while in case of rotation, it retards significantly. For the validation of this study, a comparison of our results with previous published work is conducted.
