摘要：

Electric field effect on nanofluid forced convective heat transfer in an enclosure with sinusoidal wall is presented. Control Volume based Finite Element Method (CVFEM) is utilized to simulate this problem. Fe3O4-ethylene glycol nanofluid is used as working fluid. Numerical investigations are conducted for several values of Reynolds number, nanoparticle volume fraction and supplied voltage, Results show that supplied voltage can change the flow shape. Coulomb force causes isotherms to be denser near the moving wall. Heat transfer rises with augmentation of supplied voltage and Reynolds number. The effect of electric field on heat transfer is more pronounced at low Reynolds number. (C) 2015 Elsevier B.V. All rights reserved.
