RÉSUMÉ

This paper presents some new thinking about the possible effects of the electrode geometry on the electrohydrodynamic (EHD) enhancement of two phase heat transfer, especially boiling heat transfer. A hypothesis on the dependence of the enhancement effect on the geometry of the EHD electrode system in two phase heat transfer is made. For boiling, a conceptual model regarding the effect of EHD force on the bubble movement and hence enhancement effect is built. Furthermore, a semi-symmetrical electrode geometry is suggested to assess the hypothesis. The outcome of this study can hopefully form the basis of design of practical EHD heat exchangers.
