Abstract

The current explores the consequences of radiative heat and the variable porosity on the steady flow of an incompressible hybridised nanomaterial comprising hybrid alloy nanoparticles (AA7072, AA7075) along with water (H2O) as the conventional fluid. The proposed investigation is performed within the framework of the Riga plate. Because of the complimentary benefits of nanoparticles, hybrid nanofluid is used to improve the efficacy of heat transfer fluids. The flow scenario is characterized by a system of dimensional, nonlinear differential equations renewed to a set of nonlinear dimensionless ordinary differential equations using appropriate similarity substitution. The Keller Box Method (KBM) then solves these transformed equations. Graphs have been used to inspect the effects of changing physical factors on fluid flow, temperature, and other important measurements. This study evaluates the dependability of the results by comparing them to previous research. The results reveal the significant impact of flow medium inverse porosity influences both the boundary layers to the flow resistance and heat transference characteristics. The Riga plate significantly affects the fluid flow and heat transmission, leading to variations in velocity profiles and thermal gradients due to the generated electromagnetic field. Radiant heat influences become more pronounced at higher temperatures, growing heat transport for high-temperature applications. The combined effects of hybrid nanomaterials, radiative heat transfer, electromagnetic field result in affecting skin friction and the heat transfer coefficient. Finally, the hybridization of AA7072 and AA7075 aluminum alloys in the nanoliquid significantly augments thermal conductivity, resulting in enhanced heat transportation rates compared to conventional fluids.
