RÉSUMÉ

A model experiment was conducted to investigate the dynamic behavior of a liquid sheet under an electric field applied parallel to the flow direction. It was confirmed that the liquid sheet was changed into columns when the applied voltage exceeded a certain critical value. A model analysis based on a linear stability theory was then carried out to predict the critical applied voltage, and the analytical results were shown to be in good agreement with the measured values. Further, based on the above-mentioned model describing the dynamic behavior of the liquid sheet, an analytical model predicting the EHD effect on condensation heat transfer for a finned tube is presented. The predicted results are shown to be in good agreement with the experimental data on the flooding angle and the condensation heat transfer coefficient for a finned tube under an electric field.
