Heat-exchanging devices equipped with conventional thermal fluids are failing to meet the standard in terms of efficiency. The inclusion nanoparticles within a base fluid improve efficiency can be great alternative but proper understanding on interactions during heat transfer phenomena is required. This work examines between conduction and convection nanofluid water copper (Cu) particles. investigation focuses behavior nanofluid, considering impact magnetohydrodynamics (MHDs) flow over vertical surface. governing equations were non-dimensionalized by suitable transformation then solved numerically implicit finite difference method (FDM). key findings suggested that increasing magnetic parameter plummeted skin friction coefficient accelerated dissipation up 5%−10% augmenting peaks velocity as well temperature under constant volume fraction nanoparticles. In addition, boundary layer thickness also increased concurrently. Alternatively, when non-zero was considered, allowed vary, convective got enhanced. from this study will assist relevant industry identify Cu presence field order achieve best efficacy heat-exchanging unit.
