5. Workshop "Measurement Techniques for Steady and Transient Multiphase Flows"

The Forschungszentrum Rossendorf (FZR) carries on a series of workshops on Measurement Techniques for Steady and Transient Multiphase Flows with the support of the following organisations: DECHEMA / Gesellschaft für Chemische Technik und Biotechnologie e.V., Kerntechnische Gesellschaft e. V. (KTG), Technical Group on Thermal and Fluiddynamics and Local Section of Saxony, Institute of Process Technique, Process Automation, and Measuring Technique (IPM) at the University of Applied Sciences Zittau/Görlitz and the TELETRONIC GmbH in Rossendorf. The first workshop was held in 1997 and had the character of a national event. International participation started for the first time in the 2000 edition of the workshops series.

The main aim of this workshops series is to discuss recent developments and future tendencies in the field of high-resolution measuring techniques used to characterise two-phase or multi-phase flow fields. Examples are measurements of the gas-liquid interface, the characterisation of its structure and its evolution in the field of gas-liquid flows and measurements of size, shape and velocity of individual particles of the disperse phase (bubbles, droplets etc.) and their dynamics. The efforts in the measure-ments field correspond to the needs of the development of three-dimensional computational fluid-dynamics (CFD) models and computer codes. High-resolution data is necessary both for the development of geometry independent constitutive equations describing the interaction of the different phases taking part in the flow and for the validation of the CFD codes against experiments. Moreover, modern tendencies in instrumentation for industrial applications are discussed.
