摘要

In the modern era, energy has become a vital concern across all sectors, while efficient energy generation remains a significant challenge for scientists and engineers. To overcome this issue, researchers have developed ternary hybrid nanoparticles, which exhibit enhanced thermal and physical characteristics compared to conventional mono- and binary nanoparticles. Motivated by these advantages, the present study investigates the flow of a thermally radiating Falkner-Skan Casson ternary hybrid nanofluid over a permeable wedge. Moreover, the flow model is developed by considering the combined influences of magnetohydrodynamics, thermal radiation, Joule heating, and viscous dissipation. The formulated mathematical model, consisting of a system of highly nonlinear ordinary differential equations, was numerically solved using the Runge-Kutta-Fehlberg 45 (RKF-45) method in conjunction with a shooting technique. Practically, such mathematical models are widely applicable across modern engineering industries, particularly in energy conversion and thermal systems such as solar HVAC systems, solar thermal collectors, nuclear reactors, and advanced cooling technologies, where efficient heat transfer is of critical importance. Effects of pertinent parameters on flow velocity and temperature distributions are presented and discussed for three wedge positions (i.e. static wedge, forward and backward movements of wedge). Few of the pertinent results are: (a) it is noted that the skin friction coefficient increase effectively for the growing magnitude of Darcy number for all three scenario of wedge ( \(\:\alpha\:\) \(\:=-0.3,\:\:\alpha\:=0.0,\:\:\text{a}\text{n}\text{d}\:\alpha\:=0.3,\:\) ), (b) it is observed that the temperature profile increases effectively for the enlarging values of radiation parameter \(\:(Rn=0.1,\:1.0,\:2.0)\) and (c) the magnitude of Nusselt number coefficient decreases effectivly with the growing magnitude of Eckert and Prandtl number.
