A rectangular column with a controlled injection sparger where each hole can be operated independently, giving measurements clean and repeatable enough to serve as a validation case for the project’s numerical work.<\/p>\n\n\n\n

The facility is designed to investigate bubble-induced turbulence in gas\u2013liquid flows under controlled operating conditions. A transparent test section enables the characterization of bubble dynamics and their interaction with the surrounding liquid phase. High-speed imaging and advanced velocimetry techniques are used to quantify bubble size, shape, trajectories, velocities, and the liquid velocity field. Dedicated data analysis provides turbulence statistics, velocity fluctuations, and bubble\u2013liquid correlations. The facility provides high-resolution experimental data for understanding bubble-induced turbulence and for the development and validation of closure models for Euler\u2013Euler simulations.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n\n\n\n
