摘要 对变压器油圆形浸没射流冲击换热特性进行了系统的实验研究 ,分析了恢复效应、喷距、射流Re、喷嘴尺寸等因素对换热的影响 .对极小尺寸射流冲击换热情况下的一些特殊现象进行了描述 。 The heat transfer characteristics were investigated under impinging submerged circular jets of transformer oil. The factors included recovery effect, Re, nozzle-to-plate spacing, size of nozzles. Abnormal phenomena were observed from the experimental results of extremely small size jets. The mechanism behind the results was analyzed.
