Influence of EFD viscosity on nanofluid forced convection in a cavity with sinusoidal wall

Impact of Coulomb force on Fe3O4-Ethylene glycol nanofluid convective heat transfer is examined. The positive electrode is considered as moving wall. Control Volume based Finite Element Method is selected to obtain the outputs which are the roles of Reynolds number (Re), nanofluid volume fraction and supplied voltage (Δφ). EFD viscosity of nanofluid according to experimental data is taken into account. Results reveal that electric field boosts the convention mode so heat transfer rate augments by augmenting Coulomb force. Isotherms become denser near the lid wall with augment of Re and Δφ. Using electric field is more useful for lower Reynolds number.
