- Much attention has been devoted to the study of the correlation of the wet gas flow rate measurement with a Venturi meter. However, up to now a widely-accepted correlation or model is not available. In this study, a new correlation for wet gas flow rate measurement with Venturi meter based on a two-phase mass flow coefficient was proposed. The two-phase mass flow coefficient was found to linearly increase with the Lockhart-Martinelli parameter and decrease with the increase of the gas-to-liquid density ratio. It also decreased with the gas densiometric Froude number increasing. The relationships of the two-phase mass flow coefficient with the Lockhart-Martinelli parameter, the gas densiometric Froude number and the ratio of gas to liquid density were concluded. Comparisons with the existing correlations showed that the new correlation predicted the wet gas flow rate more accurately than other correlations under the following conditions: the Lockhart-Martinelli parameter ranging from 0 to 0.3, the gas densiometric Froude number from 0.6 to 4.7, the ratio of gas to liquid density from 0.01 to 0.081 and the inlet diameter of the Venturi meter from 50 to 200mm. The present work provided an alternative approach to the study on the wet gas flow rate measurement with the Venturi meter.
