Abstract
The problem of heat transportation and ternary hybrid nanofluid flow over a shrinking Riga plate, as well as the effects of non-unifi)rm heat source/sink, velocity, and thermal slip, is investigated. 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 involved electromagnetohydrodynamic (EMHD) combined with an electromagnetic surface named Riga plate, which are derived and funher reduced to ordinary differential equations to reduce the complexity of the solution. The solutions are coinputed using a user-friendly solver, bvp4c, built-in MATLAB software. The findings indicate that velocity slip, Ecken number and magnetic parameter have similar effects toward the auglnentation of temperature profiles and Nusselt number. However, the EMHD parameter forces the velocity, skin friction and Nusselt number to be diminished. Furthermore, the concentration of GO has a significant impact towards temperature profile, skin friction and Nusselt number to amplify. These findings benefit the process of advanced cooling systems, power converters and inverters tor renewable energy, electric cars and many' more.
