Title: Microscale wave breaking and airflow separation in stratified two-phase pipe flow
by: Petter Vollestad, matematisk institutt, UiO.
Abstract: We perform an experimental study of stratified gas-liquid pipe flow with the aim to detect small-scale wave breaking and its influence on both the gas and liquid phase. Particle image velocimetry (PIV) is applied simultaneously in the two phases, and a criterion based on the vorticity in the crest region is used to detect microscale breaking waves. Airflow separation is frequently observed, and the study aims to investigate the correlation between small scale wave breaking and airflow separation above waves. Results indicate that at moderate gas flow rates, microscale wave breaking has a stabilizing effect on the airflow above waves, reducing the sheltered region in the lee of the wave crest and the turbulence directly above the waves. At higher gas flow rates, no influence of wave breaking on the airflow is observed.

We will have a “mingle” meeting. There will be updates from Kristine and Per on the running of the institute. But fear not, there will also be plenty of time for informal chat and eating of cake. All are welcome to the lobby on the first floor.
Hans J. Skaug (Department of Mathematics, University of Bergen) and Mike Spagat (Department of Economics, Royal Holloway University of London) will both give a talk on December 6th at 14:15 and 15:15 in the Seminar Room 819, Niels Henrik Abels hus, 8th floor.
