A computational numerical simulation of free convection catalysts for magnetized micropolar ethylene glycol via copper and graphene oxide nanosolids

Abstract

In this study, a mathematical model simulating the flow of ethylene glycol as a micropolar fluid supported by copper or graphene oxide nanoparticles around a cylinder affected by a magnetic field is established. A computational approximation is introduced for the solution of the governing mathematical model using the Keller-Box approximation. In addition, computations are executed with the aid of the MATLAB program to obtain numerical and graphical outcomes and validate and assess them. The graphical outcomes of the influential factors on the physical quantities related to energy transmission are analyzed and discussed. According to these outcomes, all physical groups are decreasing functions of the micropolar factor. With the exception of temperature, increasing the intensity of magnetic parameters has a negative impact on the studied physical groups. The fractional volume factor increases friction forces, the Nusselt number, and the temperature while decreasing velocity and angular velocity.
