| Abstract: | Low temperature waste heat power generation model on the base of Rankine - cycle is designed and constructed, and the experiment on EHD enhancement of condensation heat transfer of dielectric fluid are conducted. CFC11 is selected as the working fluid. Relation between condensation heat transfer coefficient, heat flux and applied voltage under the condition of the different temperature is obtained and analysis is conducted on the power consumption of the supplied electric field. The results are valuable to extend the theoretical investigation of EHD enhancement of condensation heat transfer. |
