Thermal scrutinization of magetohydrodynamics CuO engine oil nanofluid flow across a horizontal surface via Koo–Kleinstreuer–Li modeling: A thermal case study

Abstract

The current investigation aims to investigate the effects of ohmic heating, heat source, and adhesive dispersion in third-grade nanofluid flowing magnetohydrodynamics (MHD) boundary layer heat transmission using the Koo–Kleinstreuer–Li (KKL) model. As a basic fluid, copper oxide nano molecules are suspended in engine oil. The controlling formulas that regulate the fields of flow and heat conduction are partial differential equations (PDEs) which are then converted into models of nonlinear ordinary differential equations (ODEs) that use the necessary similarity conversions. The resulting ODEs are numerically resolved using the Keller-Box approach. The effects of different common liquids, nano molecule sizes, magnetic parameter, Prandtl, material constant, and Eckert numbers are described using diagrams and tables for the field of motion, the field of temperature, the rate of heat transfer, and the drag force factor. The results show that the speed, drag force, and nozzle number for copper oxide engine oil nanofluids are lower than that of the basic liquid, while the addition of nanoparticles raises the temperature. The drag force factor and the rate of heat transfer are both found to increase when the material constant rises.
