Abstract
AbstractThis paper investigates the enhancement of natural convection heat transfer using hybrid nanofluids over a moving vertical plate. Two different kinds of fluids, namely \({\text{Cu}} - {\text{Al}}_{2} {\text{O}}_{3}\)/water and \({\text{Cu}}\)/water, are selected for investigation. The principal equations modelling the flow are solved using a robust finite difference numerical method. Impacts of main parameters, such as magnetic parameter, radiation parameter, Grashof number, and nanoparticle volume fraction, are analysed on skin friction coefficient, velocity profiles, Nusselt number, and temperature profiles. The numerical results are validated by comparing them with analytical correlations. The present work finds application to the cooling of nuclear reactors, microelectronics, and solar energy conservation systems.KeywordsUnsteady flowFree convectionHybrid nanofluidVertical plateFinite difference numerical methodMagnetohydrodynamics (MHD)Thermal radiation
