Summary

The results showed that this method can be used to determine the two-phase mass flow rate relatively well for the entire quality range. This method was particularly accurate in determining the mass flow rate data in the high-quality range, i.e., in annular flow. Moreover, this method also showed a reasonable accuracy in predicting the void fraction. The use of this method in predicting the two-phase mass flow rate was compared with the use of a venturi meter or a turbine flowmeter and a void fraction meter. the comparison showed that at qualities higher than 0.6, the method is superior to those that use one of the flow signals and void fraction and/or quality measurement. At lower qualities, the method still offers a fairly accurate technique for measuring the liquid-vapour refrigeration mass flow rate.
