Investigation on liquid entrainment in tee junctions with an upward oriented vertical branch was conducted. Existing correlations and test data were identified for evaluation and comparison. Theoretical analysis was carried out for the development of a new entrainment onset criterion and an entrainment rate model. Comparisons were performed with all available data with different test conditions, and the results indicated that the new correlations demonstrated a marked improvement.
