Mixed convection MHD hybrid nanofluid flow between two parallel rotating discs with joule heating and chemical reactions using bvp4c

Abstract

Several characteristics of the resulting fluid are influenced by the nanoparticle suspension. Understanding the heat transfer mechanism in nanofluids is necessary for many production and manufacturing applications. The current study examines the effects of mixed convection MHD and Joule heating on the flow of ( TiO2– GO/water) hybrid nanofluid and ( TiO2/water) nanofluids in the porous media between two parallel, infinitely spinning discs when radiation occurs. Using the “bvp4c” function in MATLAB, the governing equations are numerically solved. A graphic is used to show how important parameters affect the velocity, temperature, and concentration of nanoparticles. Finally, a table depicting the interactions between several important factors and skin friction, the Nusselt number, and the Sherwood number at the upper and lower discs is created. The findings show that while the local skin fraction drops with an increase in the mixed convection parameter, the heat transmission rate at both discs increases. Additionally, the rate of heat transmission at both the top and lower discs is reduced as the radiation and magnetic parameters increase. This study’s findings will be helpful to numerous nanofluid-based medicinal applications, architectural design systems, better oil recovery systems, and transportation procedures, among other sectors.
