Numerical analysis of EHD nanofluid force convective heat transfer considering electric field dependent viscosity

摘要

The objective of present attempt is to investigate electric field effect in Fe_3O_4-ethylene glycol nanoma-terial 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.
