Abstract
In this work, an investigation of a steady-state, incompressible, magnetohydrodynamic (MHD), ternary nanofluid flow over a stretching surface has been undertaken. The sheet is influenced by Thompson/Troian slip, in conjunction with a temperature jump effect. Titanium-dioxide, copper, and silver nanoparticles are dispersed in water to form the ternary nanofluid. The sheet has been hypothesized to undergo vertical stretching, allowing the gravitational force to induce free convection, whereas a magnetic field has been imposed transverse to the sheet’s motion. This research also considers the Cattaneo-Christov heat model in association with radiation effects. Furthermore, it is postulated that heat source/sink are present in the scenario. This configuration of fluid flow forms the basis for developing a mathematical model expressed in terms of partial differential equations (PDEs), which are reconstructed into ordinary differential equations (ODEs) by utilizing appropriate similarity relations. We finally get the non-dimensionalized equations which are then tackled using the shooting numerical scheme. A comparison of the obtained results has been made with the results acquired using the bvp4c MATLAB function to ensure the validity of the solution. The salient results reveal that an augmentation of the magnetic parameter and the silver nanoparticles concentration results in an improvement in the temperature of ternary nanofluid. However, the flow velocity and Nusselt number experience a decline due to an increased volume fraction of silver nanoparticles, whereas, skin friction coefficient value elevates. This study endeavors to achieve a deeper comprehension of complex heat and fluid flow phenomena. These insights are crucial for advancing both the theoretical models and practical applications in cutting-edge technologies. It is envisaged that better control/manipulation of ternary nanofluid velocity and temperature profiles will improve existing technologies specifically relating to managing solidification in MHD-based metal casting and designing efficient heat exchangers as well as solar collectors.
