극저온 블로워를 활용한 액체 수소 냉각 기반 간접 열교환 방식 배관 시스템의 손실 수두에 관한 연구

다국어 초록 (Multilingual Abstract)

In this study, a study on the theoretical calculation of loss of head for a piping system for indirect heat exchange using a cryogenic blower was conducted based on liquid hydrogen cooling. The loss of head was calculated to analyze whether the cryogenic blower operates normally in the system. The head loss considered in this study was divided into four types: friction loss, collision loss, and helix loss of LH₂ heat exchanger (HX) and high-temperature superconductor (HTS) coil. The loss of head calculated by introducing the theoretical method occurred in the order of loss of head on LH₂ HX, collision loss of head, helix loss of head on HTS coil, and friction loss of head. According to these calculations, the specifications of the cryogenic blower were selected, and it was confirmed that the blower operates normally in the piping system using liquid hydrogen cooling and indirect heat exchange.
