Effects of internal heat generation and Lorentz force on unsteady hybrid nanoliquid flow and heat transfer along a moving plate with nonuniform temperature

Abstract

AbstractThe aim of the studyThis study aims to explore the transient magnetohydrodynamics (MHD) boundary layer thermal convective flow of a hybrid nanoliquid past a moving vertical plate under the influence of internal heat generation and variable surface temperature.The research methodologyThe problem is modeled by coupled nonlinear partial differential equations with relevant boundary conditions. Formulated control equations are worked out using the robust implicit finite‐difference technique. The current work is validated with existing literature for special cases of the problem. The impact of important characteristics on hydrodynamic and thermal patterns, accompanied by skin friction parameter and Nusselt number, is scrutinized graphically.The major conclusion of the studyImpacts of MHD, inner thermal generation, and variable surface temperature on nanoliquid circulation and energy transport are studied. It has been found that velocity, temperature, and skin friction coefficient increase with the increase in the heat generation parameter, whereas the Nusselt number reduces with such parameter.The significance of the studyObtained results can be used in different engineering devices, including heat exchangers, solar collectors, and chemical reactors.
