The heat transfer characteristics of an electrohydrodynamically induced impinging liquid flow were studied in point-plane geometry. Points of four different metals were tested, varying the high voltage and the point-to-plane spacing. Heat transfer coefficients augmented more than 200%, with a negligible Joule dissipation. The Nusselt number on the stagnation point was successfully correlated to a dimensionless group, behaving similar to the Reynolds number in submerged jets.

Abstract
The heat transfer characteristics of an electrohydrodynamically induced impinging liquid flow were studied in point-plane geometry. Points of four different metals were tested, varying the high voltage and the point-to-plane spacing. Heat transfer coefficients augmented more than 200%, with a negligible Joule dissipation. The Nusselt number on the stagnation point was successfully correlated to a dimensionless group, behaving similar to the Reynolds number in submerged jets.File in questo prodotto:
