Abstract
Measurements on liquid holdup and interfacial area were made for cocurrent gas–liquid upflow through packed beds using four liquid systems with five different particles. Empirical correlations for the estimation of static liquid holdup, dynamic liquid holdup and the interfacial area have been developed using a data bank consisting of 49, 1337 and 129 measurements respectively. The predictive ability of the present proposed correlations was tested with the available literature data. A statistical analysis of the performance of the proposed correlations for static and dynamic liquid holdup based on the available data with a wide range of variables was also made.
