摘要

Electrohydrodynamic heat transfer enhancement in the aviation coolant PAO was examined using a concentric wire-cylinder test section. Stailiness steel (alloy 304), brss (alloy 260), and bronze (alloy 510) wire electrodes were used with both negative and positive polarity. The outer tube was 316 stainelss steel. Bronze gave enhancements over an order of magnitude grater than either brass or stainless steel, with smaller increases in pressue drop and lower electrical power requriements for both postiive and negative polarities. Several explanations are given for the differences in performance are discussed.
