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 ten times, with a negligible additional work, by means of the ion injection technique.

Abstract
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 ten times, with a negligible additional work, by means of the ion injection technique.File in questo prodotto:
