Flow boiling in liquid hydrogen, liquid methane and liquid oxygen: A review of available data and predictive tools

摘要

Flow boiling experimental data for liquid hydrogen (LH2), liquid methane (LCH4), and liquid oxygen (LO2) were compiled. The collected data represent saturated nucleate/forced convective evaporation boiling (pre-CHF), and film/dispersed droplet boiling (post-CHF). For LH2, pre-CHF data were compiled from six sources, and post-CHF data were compiled from 12 sources. Useful pre-CHF boiling data for LCH4 were found only in two sources, and no data for post-CHF boiling of LCH4 could be found. For LO2, pre-CHF (only two data points) and post-CHF data could be extracted only from a single source. The predictions of 15 pre-CHF and nine film/dispersed flow boiling correlations are compared with data for the three cryogens. The post-CHF boiling data are only compared with appropriate models and correlations based on surface geometry and orientation. Predictive methods with best agreement with experimental data are identified.
