A correlations has been developed from considerations of single‐phase flow behavior to predict pressure drop across packed beds for two‐phase cocurrent flow. The correlation does no require one of the assumptions made in previous correlations, and thus it was not necessary to relate empirically any dimensionless groups through the use of experimental two‐phase flow data. The only empiricism involved in the use of this correlation is that required in correlating single‐phase pressure drops through packed beds, an art well developed in the literature. The correlation as developed here is at least as accurate as previous correlations in this area and may be more reliable when used for two‐phase systems not previously studied experimentally.
