Thermal efficiency of the variable porosity system of viscoplastic (Casson) water-based hybrid nanofluid transport due to an exponentially elastic sheet: Computational study

Hybrid nanofluids efficiently transfer heat electronics and industrial operations by combining two nanoparticles in a base fluid. Recently hybrid nanofluids have replaced more traditional mono nanofluids flows to improve heat transmission. An assessment of hydrodynamics flow is conducted, examining the influence of Ohmic dissipation and variable porosity on two-dimensional hybrid nanofluid flow in an exponentially elastic sheet. Additionally, the thermal performance of hybrid nanofluid flow toward an elastic porous surface has been assessed in the presence of thermal radiation, Ohmic heating, and heat source. The hybrid nanofluid is made up of the suspension of two different nanoparticles, i.e. Magnesium oxide (MgO) and Zinc oxide (ZnO), in a base fluid water. Following the implementation of similarity transformations, the leading equations are converted into a series of ordinary differential equations, which are solved numerically using the Runge–Kutta fourth-order with shooting technique. The behavioral flow on heat transmission for different parameter dominance is illustrated using graphs and tables.
