Droplet Impact on a Heated Stainless Steel Surface: Influence of Camera Framing Rate.

Samuel L. Manzello, Jiann C. Yang

Abstract

The impact of a single water droplet upon a polished stainless steel surface was imaged using a Digital High Speed Camera at 500, 100, 15,000 frames per second with shutter speed set to 50 us. The camera was fitted with a 60mm micro lens to obtain the required spatial resolution to capture droplet impingement. The camera was aligned at an angle 0=33 degrees with respect to the horizontal. Surface heating was accomplished using a copper block with two miniature cartridge heaters embedded within it. The surface temperature was controlled within +/- 1 degree C using a temperature controller. The surface temperature and impact Weber number were fixed for each framing rate at T5=345 degrees C and We=165, respectively. At 15,000 frames per second, jetting was observed during breakup of the liquid film.
