| description | In this work, we present a numerical investigation of the effect of a temperature gradient on the flow characteristics of electrohydrodynamic (EHD) conduction phenomenon. The influence of temperature on the physical properties of dielectric liquids together with the dielectric force has been investigated by a dimensional simulation. To better identify the influence of different forces, a 2D asymmetric parallel electrode configuration with a temperature gradient has been considered. The effect of the dielectric force on the flow pattern and strength of EHD conduction mechanism has been investigated. In order to do this, we vary the dielectric force acting on the flow field by increasing the applied electric field strength and temperature gradient. In the process, we also discuss the effect of the dielectric force direction on the flow field. It is found that the presence of the dielectric force significantly modifies the flow pattern and strength of the system compared to the case of the Coulomb force alone in the flow field. As the applied electric field strength and temperature gradient increase, the effect of the dielectric force on the flow characteristics of EHD conduction mechanism increases. |
