Abstract

Abstract

A new model for subcooled flow boiling at low pressure has been proposed. The model considers the closure relationships of one-dimensional thermal-hydraulic codes that are important for void fraction in the channel: wall evaporation model and drift-flux model. The new model was incorporated in the current version of the ATHLET code, MOD 2.1 A. The new modified code was validated against a number of published low-pressure subcooled boiling experiments, and in contrast to the current code, shows good agreement with the experimental data.
