Abstract

To enhance heat transfer in heat exchangers, particularly when dealing with non-Newtonian and Newtonian fluids, the application of an effective external field, such as a magnetic field, can play a crucial role in achieving higher thermal efficiency. This paper assesses the free convection heat transfer of non-Newtonian nanofluids in a two-dimensional context. The fluid flows over a vertical plate, and to improve heat transfer, a uniform external magnetic field is applied perpendicular to the flow. The continuity, momentum, and energy equations are reformulated into a dimensionless form with boundary conditions at the wall (constant temperature) and subsequently solved using established numerical methods. The primary objective of this work is to determine the velocity profiles, temperature distributions, Nusselt number, and friction coefficient, as well as to analyze how heat transfer variations are influenced by the hydrodynamic and thermal boundary conditions imposed on the fluid.
