Original Abstract

The spray cooling of stainless steel plates was studied using different orientations of the cooled surface. A 1.5 mm-thick test plate was moved vertically or horizontally with a velocity of 3 m/s. Experiments were conducted with mist nozzles oriented either vertically with the spray flowing down or horizontally. The water impingement density was between 0.93– 9.68 kg m2 s-1. It was found that the heat transfer coefficient is similar for horizontally and vertically down oriented nozzles within the surface temperature range of 700–900C. The vertically down spray yields a higher heat transfer coefficient for surface temperatures below 300 C. Furthermore, it was observed that the Leidenfrost temperature is slightly higher for vertically down spray for lower water impingement densities. This shift of the Leidenfrost temperature was not observed for higher water impingement densities.
