Abstract
An ultrasonic pulse-echo instrumentation system is developed for two-phase flow applications. The technique is capable of locating instantaneously the location of a moving gasliquid interface target by measuring the round trip time of flight of the echo of a pulsed ultrasonic signal reflected upon by the interface. Digital methods are employed and fast data acquisition rates are achieved by using transient memory schemes. Data retrieval and analysis is also enhanced by using a microprocessor.
The technique was applied to horizontal air-water pipe flow system in order to measure the interfacial area and geometry; and to characterize the various flow regimes developed. The results are in agreement with some two-phase flow correlations as well as with previous experimental works using different techniques.
