Heat transfer enhancement of a Poiseuille flow by means of electric conduction phenomenon

Electrohydrodynamic (EHD) conduction phenomenon involves the interaction of electric field and flow field in a dielectric fluid medium via the process of dissociation and recombination of free charges. This paper numerically studies the effect of electric conduction phenomenon on the heat transfer characteristics of a Poiseuille flow. The numerical domain consists of six electrode pairs positioned along the tube wall. The flow is primarily generated by an external pressure-gradient imposed along the tube. The electric field and electric body force distributions and the resultant velocity fields are presented. The heat transfer enhancements are illustrated under various operating conditions.
