Abstract In the present paper, available experimental data and predictive correlations on cryogenic film boiling heat transfer are summarized and analyzed. A unified correlation formation, which could standardize the most of the existing heat transfer correlations, is used to perform comparison studies, and a series of validated correlations focusing on predicting cryogenic boiling events are reached. It demonstrates that Merte & Clark correlation and Bromley correlation are recommended to predict cryogenic film boiling heat flux at spherical and horizontal tube heaters respectively, and the deviations are within ±15% and ±8%. A preliminary data analysis indicates that Laplace reference length could be regarded as a critical diameter to distinguish tube and wire conditions. Moreover, a unified correlation without considering surface orientation effect is proposed to account for the plate heater boiling issue in the view of engineering application, and the deviations are within ±40%. Generally, the present study could provide researchers with reliable research tools to conduct cryogenic heat transfer analysis.

不同几何形状加热器液氮的薄膜沸腾传热预测

摘要 在本文中，对低温薄膜沸腾传热的现有实验数据和预测相关性进行了总结和分析。统一的相关性形成，可以标准化大多数现有的传热相关性，用于进行比较研究，并获得了一系列专注于预测低温沸腾事件的验证相关性。结果表明，分别推荐使用 Merte & Clark 相关和 Bromley 相关来预测球管和水平管加热器的低温薄膜沸腾热通量，其偏差在 ±15% 和 ±8% 以内。初步数据分析表明，拉普拉斯参考长度可被视为区分管材和线材状况的临界直径。而且，针对板式加热器沸腾问题，从工程应用的角度提出了不考虑表面取向效应的统一关联式，偏差在±40%以内。总的来说，本研究可以为研究人员提供可靠的研究工具来进行低温传热分析。
