Time-Dependent MHD Free Convective Heat Circulation of Hybrid Nano Liquid over a Vertical Porous Plate Due to Temperature Oscillation with Thermal Radiation and Viscous Dissipation

Abstract

In the current numerical simulation, the thermal transfer of viscous incompressible time dependent MHD free convective flow of hybrid nanofluid (Cu-TiO2-H2O) over a vertical porous plate with viscous dissipation and thermal radiation is examined. The system of partial differential equations which controls the fluid flow are transmuted into dimensionless equations and are solved using numerical simulation namely Galerkin Finite Element Method. The momentum and thermal consequences, coefficient of heat transfer and skin friction with Gr, M, Ec, N, t, ωt, δ2, λ – parameters for both nanofluid (Cu-H2O) and hybrid nanofluid (Cu-TiO2-H2O) flows are exposed through graphs and tables. It is revealed that heat transfer coefficient of Cu-TiO2-H2O is more effective when compared with Cu-H2O flows varying with aforementioned parameters. The current numerical computation is in good agreement with the analytical solution of the problem. This study is used in several engineering fields such as electronic cooling, heat exchangers, nanomaterial processing, environmental engineering, chemical industry.
