Abstract

Different methods for void fraction and phase distribution measurements in two-phase flow have been used in the past with limited success. In the present paper, the design of a simple single-beam, multi-detector gamma densitometer for void fraction and phase distribution measurements is described. Both static and quasi-static calibrations are presented. It was found that the present design is capable of predicting average void fractions in horizontal pipe flows to within 5% in general. Objective flow regime identification is also possible using the chordal void fluctuations. A simple process of elimination was developed for flow regime identification. The process is particularly suited for transient data reduction using computers.
