MHD flow of radiative hybrid nanofluid across a wedge influenced by melting heat transfer: Engineering application

Mono nanofluids exhibit highly favourable thermophysical properties, rendering them highly promising for many heat transfer applications. It is possible to tailor the properties of mono-nanofluids by adjusting the amount or concentration of nanoparticles. But, the mono nanofluids, which utilize only one type of nanoparticles (either non-metallic or metallic), exhibited consistent thermophysical features within a restricted range. In order to address this limitation, researchers have developed hybrid nanofluids in recent years. While mono nanofluids exhibit specific advantages, their intrinsic limitations in improving thermal performance and other essential aspects have prompted the creation of hybrid nanofluids as a viable alternative. These nanofluids are designed to rise the thermophysical properties and heat transport features of the base fluid. Hybrid formulations can leverage the advantages of several nanoparticles to create fluids with higher thermal properties, improved stability, and effectiveness in various thermal management applications. Hence, this research contributes to the dual solution of a hybrid nanofluid through a shrinking/stretching wedge influenced by melting heat impacts. The boundary of the surface permits slip velocity factor. The melting heat transfer impacts are analyzed on the wedge boundary. The efficiency of heat transport is examined with the influence of heat sink, source and thermal radiation. In order to derive the mathematical equations, ethylene glycol is utilized as the primary fluid, together with two distinct forms of nanoparticles: SWCNTs (single-walled carbon nanotubes) and CuO (copper oxide). We use the similarity method to turn the partial differential equations (PDEs) into non-linear ordinary differential equations (ODEs). The problem is highly non-linear and these equations are then numerically solved via MATLAB bvp4c function. Graphical illustrations highlight the features of physical parameters. There is a clear indication that the rate of heat transport is raised by the radiation parameter. Additionally, the Nusselt number reduces by the increment in melting temperature. Further, the velocity of the liquid increases when slip velocity factor becomes stronger.
