Interfacial area concentration is an important parameter in the two-fluid model for two-phase-flow analysis, which is defined as the total interface area per unit mixture volume and has the following local time-averaged expression: where j denotes the j`th interface that passes the point of interest in a time interval {Delta}T and V{sub i} and n{sub i} refer to the bubble interface velocity and surface normal vector, respectively. To measure this parameter, the double-sensor probe technique is commonly used. Because of the influences of the bubble lateral motions, however, the measurement results should be interpreted via a certain statistical approach.
