Analysis of Magnetohydrodynamic Oscillatory Convective Radiative Heat Flow of Reactive Nanofluid Containing MoS2 and SiO2 Nanoparticles with Velocity Slip

Abstract

This paper aims to investigate the unsteady oscillatory flow of water-based nanofluids MoS2 and SiO2 past a parallel plate channel filled with a saturated porous medium. The basic equations are solved analytically using the perturbation technique subject to the appropriate boundary conditions. A numerical evaluation of the analytical results is performed, and the effects of various physical parameters on velocity, temperature, and concentration profiles within the boundary layer are analyzed. Molybdenum disulfide MoS2 nanoparticles are well known for their low friction coefficient, good catalytic activity, and excellent physical properties. At the same time, Silicon dioxide (SiO2) nanoparticles are treated to have a porous structure, very high surface activity, and adsorption properties, which makes them suitable for developing high-capacity antimicrobial agents. Hence these nanoparticles can be considered for Nanoscale elements’ performance to make rigorous thermal quality nano liquids. Thus from engineering curiosity, the skin friction coefficient, Nusselt number, and Sherwood numbers are evaluated for significant parameters at cold and heated walls by utilizing MoS2 and SiO2 nanoparticles. It would give rise to novel features that can revolutionize biology, medicine, catalysis, and other smart fields. Furthermore, graphs and tables are used to describe a comparative study of the water-based nanofluids MoS2 and SiO2. It is found that when the radiation parameter Ra is increased by 200%, the average heat transfer rate at the heated channel wall containing MoS2 and SiO2 nanoparticles in the base fluid is decreased by 6.9% and 8.3%, respectively. Further, it is found that SiO2-water nanofluid has more effectiveness towards heat transfer compared to MoS2-water nanofluid.
