The knowledge of the interfacial area concentration is essential in the formulation of a two-phase models such as in two-fluid model. A theoretical foundation of the measurement method for the time averaged local interfacial area using a four sensor resistivity probe is presented. Based on this theory, the four sensor resistivity probe was employed for the measurement of local properties of two-phase flow such as the interfacial velocity, local interfacial area concentration and void fraction in a vertical air-water cap bubbly flow. Experimental data are presented on the radial profiles of the void fraction and interfacial area concentration at various gas flow rates. The four sensor probe measurements are checked against the global void measurement using a differential pressure. The result is very satisfactory. Theoretical profiles of the void fraction and interfacial area concentration were obtained using the pictures of cap bubbles. The theoretical predictions of the cap bubbles and the interfacial area concentration profiles compared very well with the four sensor data. 15 refs., 35 figs.
