The heat transfer characteristics of an electrohydrodynamically induced submerged impinging liquid flow are studied in a point‐plane configuration. The working fluid, HFE‐7100, is a weakly polar dielectric. Thermofluid‐dynamic conditions as close as possible to the microgravity ones are obtained by heating a confined, downward‐facing plate. Heat transfer coefficients on the plate can be stably enhanced by over 10 times, with negligible additional work, by means of the ion injection technique.
