Validation of COBRA-TF Critical Heat Flux Predictions for a Small Hydraulic Diameter Geometry Under Natural Boiling Conditions

摘要

The calculated results are in good agreement with the experimental data, with respect to CHF values, the trend of the CHF with diameter/length ratio and the oscillatory flow behavior. It is shown that COBRA-TF calculates conservative CHF values for small hydraulic geometry in the natural circulation boiling case.
