摘要：

The gas-liquid two-phase flow widely exists all over the industry sectors, such as hydraulic and wastewater treatment projects. The flow patterns and velocity field distributions can directly affect the operation devices performance, which are studied in this article employing the numerical simulation along with experimental research. A PIV experimental study of gas-liquid two-phase flow has been carried on a cylindrical experimental device, and the gas velocity vector fields are obtained accurately by image processing and particle image velocimetry technology. After considering the situations of turbulence and interphase forces, by using the Euler-Euler two-fluid model and bubble population balance model (BPBM), numerical simulations of two-phase flow are performed and compared with experiment results, the error of mathematical models is about 10%. The research result shows that the proposed model and calculation method can achieve accurate result of flowing regularity and velocity distributions in gas-liquid two-phase flow. © 2016, China Water Power Press.
