沸騰熱傳(Boiling Heat Transfer)主要是藉由氣泡的生成、液體的蒸發帶走大量的熱量達到冷卻的目的，因此設計出下圖所非之測試系統，模擬滿溢式(Flooded Type)熱交換器，希望對其中的沸騰現象(Boiling Phenomena)，作全盤的解析與探討，以期設計出高性能之滿溢式熱交換器。過去兩年，配合LDV的量測與CDD Camera拍攝(詳見照片)，在汽泡動力(Bubble Dynamic) 特性以及熱傳機制的解析上，有更一步的詳釋與探討(請見摘要)。

The influence of rotation and jet mass flow rate on the local heat transfer coefficient for a single confined impinging round jet with a fixed jet-to-wall spacing of H/d=5 was studied for the jet Reynolds number from 6500 to 26000 and the rotational Reynolds number from 0 to 112,000. The local heat transfer coefficient along the surface is measured and the effect of the rotation on the stagnation (peak) point, local and average Nusselt number, is presented and discussed. Furthermore, a correlation was developed for the average Nusselt number in terms of the parameters of Rej and ReΩ. In general, the combined jet impingement and rotation effect are shown to affect the heat transfer response. Rotation decreases the average Nusselt number values from 15 to 25 percent in outward and inward radial flow, respectively. Finally, comparisons of the present data with existing results for multijets with rotation were also made.
