MOTIVATION AND AIMS:

The current DNS and experiments confirm that the flow at large Reynolds number has a highly irregular structure, i.e. the regions with low gradients of the velocity (the non-turbulent motion) are intermittent with very narrow regions of persisting vortical and sheared structures, in which the velocity gradients are very large. The interactions of such structures may induce the violent local accelerations in the fluid. In many natural phenomena and practical applications, we can meet such a highly-intermittent flow but in the presence of the gas/liquid interface. The examples include see surface turbulence, primary air-blast atomization, the turbulence in stratocumulus clouds, industrial flows with droplets and bubbles.

Our main question is two-fold: how the flow structures induce two-phase interactions, and on what may be the signature of the interface between two immiscible fluids on the dynamics of flow structures. By bringing together researchers in various backgrounds, we propose to open discussions on the physics behind these interactions, and we hope that this will motivate the further studies. The expected audience in this Workshop is about 30 external participants. The Colloquium will be open for free attendance to students and junior researchers, although we highly expect to draw international researchers, complimentary to a score of invited speakers.
