Thompson and Troian slip effects on ternary hybrid nanofluid flow over a permeable plate with chemical reaction

Abstract

This study seeks to elucidate the electromagnetic hydro-thermal aspects of ternary hybrid nanofluid (THNF) (MoS2-SiO2-GO/water) flow over a permeable plate in the presence of Thomson and Troian slip, suction/blowing, and chemical reaction. Through the utilization of similarity transformations, the nonlinear partial differential equations (PDEs) representing the conservation of mass, momentum, energy, and concentration, are converted into ordinary differential equations (ODEs). The subsequent step involves solving these ODEs utilizing the bvp4c technique in MATLAB. The detailed graphical representations precisely elucidate the action of diverse parameters, such as Hartmann number, electric parameter, velocity slip parameter, Lewis number, critical shear rate, suction/blowing, thermophoresis, and Brownian motion parameter on the velocity, thermal, and concentration profiles. The momentum and temperature distributions respond oppositely to the parameters Hartmann number, electric parameter, and suction/blowing. Also, the absolute values of Nusselt and Sherwood numbers increase with elevated critical shear rate, velocity slip, and suction/blowing parameter but decrease with higher Lewis number and chemical reaction parameter. Moreover, adjusting the velocity slip parameter from 0.2 to 0.6 results in a 24.14% decrease in the skin friction coefficient and a 16.79% increase in the local Nusselt number.
