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 20 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 important tool for process analysis, optimisation and design. Essential 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 area is still in the stage of development. Important for model developments are theoretical analysis, direct numerical simulations and detailed experiments.

The Workshop will be co-sponsored by the ERCOFTAC (European Research Community on Flow Turbulence and Combustion). Young Ph.D. students may apply for financial support, which was provided by ERCOFTAC.
The Workshop will be held at the Centre of Engineering Sciences of the Martin-Luther-University Halle-Wittenberg.
The main objective of the Workshop is to bring together researchers working in the field of dispersed multiphase flow on a theoretical, numerical or experimental basis. Oral presentations and posters in the following areas are most welcome for the Workshop:
During the 4-day Workshop 40 presentations, each 30 min including discussion can be accommodated. Additionally, about 15 posters may be accepted.
The selection of oral presentations and posters will be based upon an abstract of one DIN A4-page. The abstracts and any related correspondence should be sent to Prof. Dr.-Ing. M. Sommerfeld.
Test Case Calculations
An additional objective of the Workshop will be related to the validation of numerical predictions obtained by different model approaches and numerical codes. These validations will be based on pre-defined test cases for which experimental or numerical results (e.g. direct or large eddy simulations) exist. Several test cases will be selected and made available to the interested groups approximately four months prior to the Workshop on the homepage of the organisers (www-mvt.iw.uni-halle.de/english/index.php). The test cases are generally blind test cases and only boundary and inlet conditions will be provided. The following test cases are tentatively planned:
During the Workshop, the various numerical results for the test cases will be exhibited. The presentations are followed by a round table discussion to examine the performance of the various computer codes and models. The test case calculations can be regarded as a challenge to approach more complex problems in two-phase flow predictions and will hopefully stimulate further improvements and developments of numerical methods and models. After the Workshop the test case results will be also displayed at the homepage of the organiser.
The number of groups participating in one test case calculation is limited to about five. Any questions regarding the test cases may be sent to Prof. Dr.-Ing. M. Sommerfeld.
The registration fee for the Workshop is 300 Euro, which includes the proceedings, refreshments during the breaks, lunches, an excursion and a common dinner in a historic place of the region. The registration fee should be paid by bank transfer. An invoice or receipt will be issued after the final registration.
