A method for developing correlations for subcooled flow boiling heat transfer and its application to water

Highlights: •Develops a systematic method for subcooled flow boiling heat transfer. •Proposes a correlation for subcooled flow boiling heat transfer of water. •New correlation predicts the database with an MAD of 9.1%. •The method is substantiated and proved to be effective. -- Abstract: A systematic method for developing correlations for subcooled flow boiling heat transfer was proposed. On the base of the method, a new correlation for subcooled flow boiling heat transfer of water is developed using a database containing 1184 data points from 14 published articles. The predictions of the new correlation agree with the database very well, with a mean absolute deviation (MAD) of 9.1% and 93.0% of the data within ±20% error band, which proves the effectiveness of the method.
