摘要

jet impingement cooling was investigated on aflat heating surface placed in a flow channel, including single jet cooling, in-line double jet cooling, and combined crossflow and jet cooling; cross-flow cooling was a baseline for comparison. In addition, the in-line double jet cooling was explored with various jet distances. Local Nusselt number distribution was experimentally achieved by the liquid crystal method, and the measurements were carried out under various jet pressures ranging from 1 bar to 4 bar. It was found that heat transfer depends on the jet distance because one jet may produce a crossflow effect on the other jet, affecting the formation of longitudinal vortices which could enhance heat transfer. It was seen that in comparison to the crossflow cooling, the average Nusselt number is enhanced by 110%, 150%, and 380% by the single jet cooling, the in-line double jet cooling, and the combined cooling, respectively, and correspondingly the maximum Nusselt number is enhanced by 160%, 240%, and 540%, respectively. In the combined cooling, there is a deflection distance ranging from 0 mm to 10 mm depending on the jet pressure.
