Velocity and thermal slip impact towards GO-MoS2/C3H8O3 hybridity nanofluid flowing via a moving Riga plate

Abstract

This study addresses the flow of a non-Newtonian hybrid nanofluid that uses glycerine (C3H8O3) as the conventional fluid with graphene oxide (GO) and molybdenum disulfide (MoS2) as the nanoparticles, taking into account the effect of the slip on a shrinking Riga plate. Proper similarity equations are selected to reduce the partial differential equations (PDEs) to ordinary differential equations (ODEs) with boundary conditions. Using bvp4c software in MATLAB, the suggested model is computationally analysed to obtain the results for the frictional force coefficient, local Nusselt number, entropy production, rapidity distribution, and temperature outline based on several parameter effects. As speed and thermal slippery are enhanced, the temperature of the fluid becomes colder with the range of 7.01–11.28% and 7.35–10.2%, respectively. Graphene oxide is proven to be an excellent conductor to transfer heat into the fluid as it grows the temperature by a percentage ranging between 4.13% and 10.22%.
