Analysis of fluctuating heat and current density of mixed convection flow with viscosity and thermal conductivity effects along horizontal nonconducting cylinder

Abstract

Due to excessive heating, various physical mechanisms are less interested in engineering and modern technologies. To reduce excessive heating, the aligned magnetic field acts like a coating material to insulate the heat which is a very important mechanism in modern technologies. To solve this problem, the primary goal of the current analysis is to utilize magnetization normal to the surface. Numerical simulations have been made of the magnetohydrodynamic convective heat-transfer phenomena of electrically conductive fluid flow down the horizontally non-magnetized heated cylinder. The associated non-linear PDEs that control fluid motion can be conveniently represented by using the finite-difference algorithm and primitive element substitution. The numerical outcomes are deduced in graphs and tabular form with the help of FORTRAN program. The distinct parameters in the flow model are affected by physical features such skin friction, heat transfer, and current density for velocity profile, magnetic field profile, and temperature profile together with their slopes. The current magnetohydrodynamics and thermal problem is very important in the fields of MRI resonance sequences, artificial heart wolves, internal heart cavities, and nanoburning technologies. Additionally, the increase in Prandtl Pr leads to a reduction in skin friction and heat transmission, which is physically consistent, due to frictional forces between viscous layers with lesser magnitude.
