Heat absorption/generation effect on MHD heat transfer fluid flow along a stretching cylinder with a porous medium
Abstract
The current study reveals the impact of MHD heat transfer properties of an incompressible viscous fluid were numerically solved across a continuously expanding horizontal cylinder immersed in a porous material in the existence of internal heat production/sink. The partial differential equations which govern the fluid flow with boundary constraints were converted to a collection of non-linear ODE’s with the aid of similarity variables and then numerically solved by using Keller-Box approach. The components of fluid velocity, temperature, as well as friction factor, and rate of heat transfer were all calculated numerically. Graphs and tables illustrate the fluid velocity and heat transfer properties for several Prandtl numbers, and magnetic parameters. The main goal of the current findings is to examine how the magnetic field M, Pr, and the heat absorption/generation factor Q influence the velocity and temperature gradients along a stretching cylinder. It is projected that the rise in the curvature parameter and the porosity factor would contribute to the enhancement of the temperature gradient in the boundary layer area around the cylinder.
