The series of Workshops started in 1984 at the Institute of Fluid Mechanics of the University of Erlangen/Nürnberg. The participation was limited to only a few people working in the field of particle dispersion in turbulent flows. An important objective was the performance and discussion of numerical calculations for pre-defined test cases. During the past 30 years numerical calculations of dispersed multiphase flows have received considerable interest in research and technical or industrial applications. For numerous companies in the process industries (e.g. chemical industry or food industry) computational fluid dynamics (CFD) for multiphase flow has become an essential tool for process analysis, optimisation and design. Most important for reliable numerical calculations is the modelling of the underlying elementary processes occurring on the scale of the particle, such as particle transport in turbulence, particle-wall collisions, inter-particle collisions, agglomeration, droplet/bubble collisions and coalescence as well as heat and mass transfer. This field is still in the stage of development. Important for model developments are theoretical analysis, direct numerical simulations and detailed experiments.
