Measurement of two-phase refrigerant liquid-vapour mass flow rate. 1. Venturi and void fraction meters.

Author(s) : ABDUL-RAZZAK A., SHOUKRI M., CHANG J. S.

Summary

The use of a venturi meter for the measurement of refrigerant liquid-vapour mass flow rate in a horizontal pipe is presented. Various models that utilize the output of the venturi flowmeter and the measured void fraction and/or quality to calculate the two-phase mass flow rate were examined. It was found that the applicability of the various models is dependent on the quality range. When the quality is less than 50%, the use of the momentum density model provides the best accuracy. For higher qualities, the use of the homogeneous equilibrium model is recommended.
