IMPEDANCE IMAGING RELATIVE TO GAS-LIQUID SYSTEMS

Determining interfacial area density in two-phase, gas-liquid flows is one of the major elements impeding significant development of predictive tools based on the two-fluid model. Currently, these models require coupling of liquid and vapor at interfaces using constitutive equations which do not exist in any but the most rudimentary form. This paper describes the theory of impedance imaging of two-phase mixtures and summarizes bench-type experiments utilized in its development, testing, and feasibility evaluation.
