Single-phase heat-transfer characteristics of submerged jet impingement cooling
Abstract
The effect of jet impingement and the subsequent submersion of the jet on the heat-transfer coefficient were determined experimentally. Experiments were carried out with a circular jet for different H/d ratios, jet velocities, and submerged and not-submerged cases. Results indicate that for the submerged jet the heat-transfer coefficient can be diminished by as much as 50 percent, the surface temperatures can rise by as much as 33 percent, and the heat-transfer coefficient can considerably vary depending on the H/d ratio.
