Thermal transport of magnetized nanoliquid flow over lubricated surface with activation energy and heat source/sink

Abstract

Nanofluids may help enhance heat transfer if their thermal distribution is studied near lubricated surfaces. In view of the above scopes, this investigation examines the mass and thermal distribution of a magnified nanofluid flowing toward a lubricated surface. The mass equation describes the activation energy and chemical reaction, whereas the thermal equation is utilized to elucidate the heat source/sink impact. This investigation provides novel elements such as convective conditions, slip impact, and zero mass thermal movements near the wall. The boundary layer equations are used to construct the physical problem of the flow and are then converted into dimensionless forms by applying the necessary variables. Numerical solutions to transmuted equations are achieved using the RKF-45 technique and the shooting operation only for the power-law index $m=\raisebox{1ex}{$1$}\!\left/ \!\raisebox{-1ex}{$2$}\right..$ The outcomes show that concentration and thermal profiles show deflection while the velocity profile has the opposite trend in the presence of slip factor. The study has significant practical value because of its widespread applicability in hydraulics, heat transfer, production, and polymer processing.
