Abstract

Abstract: The hybrid nanofluid is extensively used in manufacturing for industrial uses because of its exceptional property of enhancing the heat transfer process. The purpose of the present work is to find novel explanations for the behavior of thermal radiation and inclined magnetohydrodynamics effects on the convective viscoelastic flow of water Al2O3–Cu hybrid nanofluids over an accelerating permeable surface with mass transpiration. The viscoelastic liquid concept is postulated with the benefit of hybrid nanofluids employing conventional flow patterns that are impacted by the magnetic field. Thermophysical properties of Al2O3–Cu and water are employed. Nonlinear PDE for momentum, temperature, and concentration are converted into non-dimensional ODE by employing the proper similarity transformations. The current study is reported to be in very good accordance with earlier research. The velocity field and energy distributions were depicted graphically to show the influence and typical behaviors of physical factors such as the viscoelastic parameter, the Richardson number, the radiation number, etc. In industrial applications, the temperature distribution influenced by radiation is quite important, specifically in accelerated plates where cooling the liquid is necessary to achieve the desired outcome. © Pleiades Publishing, Ltd. 2024.
