Outline of Final Research Achievements

Development of an accurate turbulence model for predicting bubbly flows are in demand for efficient design and development of equipment in which bubbly flow takes place. Understanding turbulence structure in bubbly flow is therefore necessary for the development. In this study, spatiotemporal filter velocimetry (SFV) is improved and coupled with photobleaching molecular tagging velocimetry for highly accurate velocity measurement with high spatial and temporal resolutions to capture turbulence structures in bubbly flows. The improved SFV is applied to measure turbulence properties and turbulence kinetic energy budgets in bubbly flows in a vertical square duct. Effects of presence of bubbles on turbulence properties and applicability of available turbulence models for single-phase flows to bubbly flows are discussed based on the measured data.
