The main idea in the present study is to reduce the power consumption by using a partially-coated electrode, and the experimental data on heat transfer coefficients and flooding angles are presented. The results indicate that, by using such an electrode, the enhancement ratio remains at almost the same level as that of a bare electrode but the power consumption can be markedly decreased. Within the present experimental range, the condensation heat transfer coefficient on the finned tube with the partially-coated electrode reaches a value about 3 times larger than that without the electrode. In addition, a model is presented for the EHD effect on the flooding angle, and it was confirmed that the prediction from the model is in good agreement with the experimental data.
