Abstract
The current study explores the effects of radiative heat and 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 complementary benefits of nanoparticles, a 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 reduced 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 the flow medium inverse porosity on both the boundary layers and the flow resistance and heat transfer characteristics. The Riga plate significantly affects the fluid flow and heat transfer, leading to variations in velocity profiles due to the generated electromagnetic field. The influence of radiative heat becomes more pronounced at higher temperatures, increasing heat transport for high-temperature applications.
