INTRODUCTION Flows involving two phases can be found in many industrial applications. Models that can accurately predict the behaviour of these ows in complex physical situations such as turbulent ow with rotation, and unsteady turbulent two-phase ows, are lacking. Numerical simulation of the detailed behaviour of the drops or bubbles in a complex and unsteady turbulent ow can provide a fundame...

A measurement technique with a combination of PIV and LIF is suggested to measure gas-phase liquid phase separately resolve flow structures bubbly jet. In the jet, distribution bubble population shows Gaussian-like function but translated outward. Spreading nature each does not correspond other due lack number bubbles be redistributed.
