Heat transfer enhancement of EMHD GO-MoS2-Ag/H2O flow toward shrinking Riga plate with velocity and thermal slips impacts

This study investigates the heat transport and flow of ternary hybrid nanofluid over a shrinking Riga plate, considering the influences of non-uniform heat source/sink, velocity slip, and thermal slip effects. The nanometals used in this research for the ternary hybrid nanofluid are graphene oxide (GO), molybdenum sulfide (MoS2) and silver (Ag) with fluid-based water (H2O). The governing equations also involve electromagnetohydrodynamics (EMHD) combined with an electromagnetic surface named Riga plate, which are derived and further limited to ordinary differential equations to reduce the complexity of the solution. Solutions are computed using a user-friendly solver bvp4c built in the MATLAB software. The findings indicate that the velocity slip, Eckert number and the magnetic parameter produce similar effects on the augmentation of temperature profiles and Nusselt number. However, the EMHD parameter forces the velocity, skin friction and the Nusselt number to decrease. Furthermore, the concentration of GO has a significant impact on the temperature profile, skin friction and Nusselt number to increase. These findings are particularly advantageous for the development of advanced cooling technologies, as well as for enhancing the efficiency of power converters and inverters used in renewable energy systems.
