Application of Electric Field for Augmentation of Ferrofluid Heat Transfer in an Enclosure Including Double Moving Walls

Abstract

Due to employing electric field, nanofluid heat transfer enhances. This phenomenon in a porous geometry has been simulated in this paper. To augment heat transfer, the radiation term is included in the model. Ethylene glycol nanofluid is considered as the homogenous model. Electric field and shape of nanoparticles can affect the properties of ferrofluid. CVFEM is proposed for simulating the treatment of EHD flow. Voltage, permeability, radiation parameters, and nanoparticles' shape are important variables. The results prove that the platelet shape leads to the highest convective flow. As electric force enhances, temperature gradient augments. Greater permeability leads to more convective flow.
