The lectures offered an extensive view of the Institute's successful history, including the presentation of the research project C-Image, which was accompanied by the Institute for many years.  The focus of the second session was the special cooperation and solidarity with Japan, especially with Keio and Kobe University. There was also an insight into the research of reactive bubble currents. Also the long and well networked cooperation between research and industry was the topic of a lecture. The presentations were rounded off by the presentation of the new image film of the Institute for Multiphase Flows.
