Abstract

The present work is devoted to the experimental study of bubble-saturated free and impinging turbulent jets (Re = 12,000) by using a planar fluorescence-based technique for bubble imaging, combined with PIV and PTV methods for the velocity measurements. The bubble jet flows were investigated under the various volume gas fractions. On the basis of 10,000 measured spatial distributions of the instantaneous velocity fields of the both phases and local gas fraction, the statistics on the turbulent fluctuations in the jets flows was calculated, including mixed one-point correlations. The paper reports the effects of volume gas fraction on turbulent fluctuations in liquid phase (suppression or enhancement) for free and impinging jet flows.
