RECENT DEVELOPMENTS IN EHD ENHANCED HEAT-TRANSFER

This paper considers that the case for using electrohydrodynamic (EHD) enhancement of heat transfer has been established, especially in ther modynamic renewable energy applications where temperature levels are r elatively low. It goes on to establish the basis on which nucleate boi ling heat transfer is enhanced by EHD forces at surfaces designed to i mprove condensation, giving experimental results for a six-tube, shell /tube heat exchanger boiling R12 at ''lo-fin'' surfaces as well as for single-tube tests using ''Thermoexcel'' and ''Gewa-T'' surfaces.
