Abstract: 

In this study, the flow and temperature fields affected by electric field applied to the fine wire are numerically investigated for the incompressible, turbulent, and steady flow over a single slot. The numerical modeling is based on solving electric, flow, and energy equations with the finite volume approach. The computed results are firstly compared with the experimental data in case of flat plate and the results agree very well. Then, the effect of different parameters such as the applied voltage, Reynolds number, and the emitting electrode position on the heat transfer coefficient and pressure drop is evaluated. The numerical results show that the heat transfer coefficient with the presence of electric field increases by incrementing of the Reynolds number but then decreases. And it also increases by the incrementing of the applied voltage. Moreover, the reduction of distance between the emitting electrode and the slot edges can obviously effect on the heat transfer enhancement, power consumption and pressure drop.
