높은 과냉각 유동비등 조건에서 Hypervapotron 히트싱크의 열전달 성능예측 연구

다국어 초록 (Multilingual Abstract)

Because the Hypervapotron (HV) heat sink is used to cool a large area of the tokamak, it is very important to predict the heat transfer performance of the HV heat sink in predicting the thermal efficiency of the fusion power generation system. Therefore, in this study, the heat transfer performance of the HV heatsink in three flow regimes was experimentally evaluated. The effect of system parameters on heat transfer performance under sub-cooled flow conditions was evaluated, and the analysis was focused on changes in heat transfer mechanism. In addition, the existing sub-cooled flow boiling heat transfer correlations were evaluated for each regime. However, most of the correlations were under-predicted because the secondary flow due to the fin structure of the HV heatsink improved the heat transfer performance. These evaluation results show that research on the development of heat transfer correlation of HV heat sinks is essential as future work.
