ABSTRACT
The application of the electrohydrodynamic (EHD) technique on boiling heat transfer enhancement outside a single tube and a tube bundle was investigated experimentally. A tube bundle with seven tubes and a single tube have been made as test sections. R11 and R123 were used as working fluids. The test tube was a smooth copper tube with 25 mm outside diameter (OD) and 400 mm length. Six copper wires, each with a diameter of 2 mm and located 5 mm away from the heat transfer surface, served as the high-voltage electrodes. The electrodes were oriented at 60° intervals. Comparison between the EHD enhancement factors of different test sections and different working fluids was conducted. The results show that the EHD enhancement factor of the single tube is greater than that of the tube bundle, R123 has a much better response to the EHD effect than R11, the EHD enhancement factor decreased with the heat flux, and the power consumption by EHD high voltage supplier is different for R11 and R123.
