摘要：

The objective of present attempt is to investigate electric field effect in Fe3O4-ethylene glycol nanomaterial force convective heat transfer. Viscosity of nanomaterial depends upon electric field effect. Relevant mathematical formulation is completed. Control volume based finite element method (CVFEM) is employed for the numerical simulation. Emphasis is given to the outcomes of nanofluid volume fraction, supplied voltage and Reynolds number. Clearly flow pattern depends upon supplied voltage and such effect for low Reynolds number is more sensible. Thermal layer thickness close to bottom is thinner for larger Reynolds number. Heat transfer rate is increasing function of both supplied voltage and Reynolds number. (C) 2016 Published by Elsevier Ltd.
