Abstract

Abstract

In order to demonstrate the accuracy and applicability of the two-group interfacial area transport model for rectangular channel, the transport characteristics of gas-liquid two-phase interface in rectangular channel under vertical condition were experimentally studied by using four-probe conductivity probe measurement method, and a large number of experimental data such as time-average void fraction and interfacial area concentration were obtained. The experiment was conducted in normal temperature and pressure with water and air as the working medium. The test sections of the channel were made of transparent acrylic material with a cross section of 10 mm×200 mm, and converted velocities of gas and liquid were 0.047-2.014 m/s and 0.315-4.416 m/s, respectively. Flow patterns involve bubbly flow, cap-turbulent flow and churn flow. On this basis, eight experimental conditions were selected to verify the two-group interfacial area transport model for rectangular channel, and the bubble interaction mechanism affecting the interfacial area transport model was analyzed. The results show that the relative errors of bubble interfacial area concentration and void fraction in group 1 and group 2 are within 10%, which verifies the correctness of the two-group interfacial area transport model for rectangular channel.
