Influence of solar radiation and an electric force on nanofluid convection inside a porous sector cavity

Abstract

Using novel numerical techniques, this paper estimates the effect of EHD force on ferrofluid treatment. Iron oxide additives of various nanoscale forms and dimensions are added to the operating fluid. Because the percentage of nanoparticles exceeds 0.06 and the slip velocity is disregarded, the features of the carrier fluid were modified using an empirical model. The left and bottom surfaces of the moving walls had the highest temperatures and voltages. A non-Darcy presumption was that the region was permeable. A combined FVM and FEM method was utilized to solve this issue. Due to the application of an electric force, the nanofluid is able to move more quickly, and two primary vortices combine to form a single, stronger vortex. As voltage increases, Nu increases by approximately 125.52%. Utilizing greater permeable medium results in a stronger wall collision and a 113.29% increase in Nu. Nu increases by approximately 3.69% when a nanoparticle with a greater shape factor than the sphere is utilized.
