Abstract

In this paper, we study micro process of circular impinging jet in detail, for further recognizing macro heat transfer mechanism. Well-defined boundary between impinging jet zone and parallel-flow zone lies on the point away from 1.5 multiple circular jet diameter of the jet center through numerical simulation by UDF of Fluent software. Bubble content is very low and the main boiling mechanism is nucleate boiling heat transfer in the jet impingement zone. And yet characteristics are high bubble, rather stable flow content and transition boiling major in the parallel-flow zone.
