Abstract
An estimate of interfacial areas between the liquid and gas, liquid and wall, and gas and wall in two phase flow is determined using a standard 2D sensor in a fashion to infer 3D information about the liquid/vapor profile when the sensor length is much longer than the diameter. Cross-sectional flow areas for the gas and liquid are also estimated as a function of the axial dimension of the sensor, and the centroid of the mass in the sensor element can also be estimated. An electric capacitance tomography (ECT) system creates tomograms of the flow inside a sensor, and estimates of 3D physical area information are produced from the tomograms.
