This research aims to develop a deep learning framework for accurate prediction of critical heat flux (CHF) in microchannel flow boiling.
Constructed a comprehensive CHF database for structure-enhanced microchannels.
Developed a deep learning-based prediction framework incorporating physically motivated input features.
Used an adaptive weighted loss function to improve prediction in low-power operation conditions.
Applied SHAP analysis for interpretability and validation of the model.
Achieved mean absolute relative error (MARE) ≤ 7.4% in CHF predictions.
Demonstrated a coefficient of determination (R²) exceeding 0.99.
Ensured robust performance by simplifying input to basic operational and geometric parameters.
Confirmed learned feature importance aligns with established physical understandings of CHF.
