Heat and Mass Transfer in 3D MHD Flow of EG-Based Ternary Hybrid Nanofluid Over a Rotating Surface

This study analysed the heat and mass transfer in magnetohydrodynamic ternary ethylene-glycol-based hybrid nanofluid over a rotating three-dimensional surface with the impact of suction velocity. The transport equations are transmuted from partial into ordinary differential equations and subsequently solved numerically using the bvp4c solver which operates the finite difference code that executes the three-stage Lobatto IIIa formula of fourth order. The effects of the emerging parameters on the dimensionless velocity and temperature are displayed through various graphs and deliberated. Besides, the effects of some selected physical parameters on the skin friction coefficient and heat transfer are presented in a tabular form and discussed appropriately. Setting some parameters to zero reduces the current problem to some of the existing problems in the literature, and the results obtained in this current study showed an excellent agreement with related published studies. The result showed that increasing Coriolis force lowers the absolute magnitude of the skin friction coefficient in x and y directions and convective mass transfer whereas the heat transfer appreciates in the presence of the rotation parameter. Besides, the stretching parameter decelerates the flow of the ternary hybrid nanofluid in the x direction and also reduces the surface temperature while the magnitude of the skin friction coefficient increases with the stretching parameter.

Automated summary

This study analyzed the heat and mass transfer in a rotating surface with magnetic hydrodynamic ternary ethylene-glycol-based hybrid nanofluid, considering the impact of suction velocity. The transport equations were transformed into ordinary differential equations and numerically solved using the bvp4c solver. The effects of different parameters on velocity and temperature were displayed through various graphs. The results showed that the Coriolis force and stretching parameter had opposite effects on the skin friction coefficient and heat transfer.
