Prediction of two‐phase pressure drop using published correlations and a wide data base showed that no single correlation could predict across the whole range of possible flow patterns. Particular difficulty was found in attempting to predict the intermittent SI and BTS patterns. However, successful prediction was achieved for the St + RW, St + RW + D, D and A + RW patterns. Two‐phase pressure drop predictive correlations were extended to the three‐phase situation. Detailed evaluation identified three correlations which gave reasonable prediction of intermittent flow pressure drop. An adaptation is presented that enhances the prediction of these correlations for three‐phase flow. The separated three‐phase patterns could not be predicted to an acceptable standard using these types of correlations.
