“…The method of an implicit finite difference scheme, specifically Crank-Nicholson, is inducted to draw the solutions for Equations (12)(13)(14) along with the conditions in Equation (15). The extremity of this scheme leads to a tridiagonal system, which is resolved by the Thomas algorithm from Carnahan et al 32 The steady state is attained if the absolute difference between the two successive values differs only in the fifth decimal place.…”

This study numerically scrutinizes the boundary layer flow of an electrically conducting and viscous dissipative fluid past an impulsively started permeable vertical cylinder together with thermal radiation. The solutions of the governing problem are accomplished using the Crank‐Nicholson scheme. The impressions of pertinent parameters on the flow patterns of the fluid particles as well as on the velocity, temperature, and distributed regions are captured and visualized three‐dimensionally.

“…Zhang et al, by considering the magnetic field and radiation heat transfer and using finite volume method (FVM) investigated the Hall effects on the natural convective heat transfer and concluded that with the existence of magnetic field and the enhancement of Hall parameter, the fluid flow and heat transfer are improved and also, by weakening the magnetic field, the Hall parameter has less influence on the heat transfer. Ahmed et al investigated the effects of radiation and viscous distribution on the natural convective heat transfer by considering a magnetic field in a two‐dimensional porous square enclosure by using the Line method. The top and bottom sides of the enclosure are adiabatic and the left side is hot and the right side of the enclosure is cold.…”

In the present study, the natural convective heat transfer in the turbulent flow of water/CuO nanofluid with volumetric radiation and magnetic field inside a tall enclosure has been numerically investigated. The thermophysical properties of nanofluid have been considered variable with temperature and the effects of Brownian motion of nanoparticles have been considered. The main objective of this work is an investigation of the effect of using water/CuO nanofluid and presence of magnetic field on turbulent natural convection in three types of enclosures (vertical, inclined, and horizontal) by considering the volumetric radiation. The governing equations on turbulent flow domain under the influence of the magnetic field and by considering the combination of volumetric radiation and natural convection have been solved by a coupled algorithm. For validating the present research, a comparison has been carried out with the laminar natural convection flow under the influence of the magnetic field and radiation effects and also, the natural turbulent convection flow of previous studies and a proper coincidence has been achieved. The results indicated that by increasing volume fraction and Hartmann number the average Nusselt number enhances and reduces, respectively. By adding 1% CuO nanoparticles to the base fluid, heat transfer improves from 10.59% to 17.05%. However, by increasing the volume fraction from 1% to 4%, heat transfer improves from 1.35% to 4.90%. By increasing Hartmann number from 0 to 600, heat transfer reduces from 9.29% to 22.07%. Also, the results show that the ratio of deviation angle of the enclosure to the horizontal surface has considerable effects on heat transfer performance. Therefore, in similar conditions, the inclined enclosure with a deviation angle of 45° compared to the vertical and horizontal enclosure has better thermal performance.
