(Lisbon Symposia会议论文)用于热传递应用的碰撞合成射流的高动态范围全场湍流度测量

For applications requiring high local heat transfer rates, recent research has shown that impinging synthetic jets perform comparably to continuous jets, yet without needing external mass flow input. In spite of recent attention, the understanding of synthetic jet heat transfer mechanisms remains incomplete. The heat transfer performance strongly depends on flow conditions (e.g. Reynolds number, stroke length), geometric parameters (e.g. jet-to-surface distance, orifice shape). Furthermore, vortex trains of adjacent synthetic jets can interact to establish flow vectoring and significant heat transfer enhancements. Most parameters (stroke length, jet-to-surface distance, phase lag between adjacent jets) have a highly non-monotonic influence on heat transfer performance.
