- a one week summer school (21st July - 26th July),
- a five weeks research session (28th July - 29th August).
During the first week, a classical summer school is proposed. It consists in several lectures given by leading scientists and related to the topics of the research projects. The remaining 5 weeks are dedicated to working on the research projects, after a daily morning seminar. Cemracs '08 will host around 20 research projects on the topic of computation fluid dynamics sponsored by industrial or public research funds.
Each participant will work in a team on a project proposed by an industrial or an academic partner. Each team will be composed of young researchers assisted by one or more senior researchers. The commitment for the young researchers is to be present for the whole period of the research session. The commitment for the senior researchers is to ensure the management of the project, that is mainly to precise definition of the subject and supervision of the project. Other visiting scientists, interested in the ongoing research, can be associated to the program for shorter periods and are, of course, welcome.

Scientific Topic of Cemracs '08
Cemracs '08 will be dedicated to the study of complex fluids in which some entities evolve and may have an effect on the fluid behaviour, for example two-phase flows with high contrast of properties. Among many other fluids, we can consider biological fluids (blood: red/white cells-plasma, breathing: air-aerosol), vesicle or polymer suspensions, mudflows, lava (up to their dry limit)...
The involvement, during this Cemracs, of physicists experts in such fluids, will allow us to first work on modelling aspects, mainly by using direct simulation of the coupled equations of the fluid and the entities. Models will then be validated by the analysis of the results obtained by both direct simulation and experiment. Direct simulations will also be used as a tool to develop new computing strategies and to enhance the performance of existing numerical methods. This will allow to take into account quite precisely some microscopic phenomena (weakly deformable entities, interaction between entities, like lubrication, short-range attraction, etc.) and to accurately quantify their influence on the fluid-entities coupling. This will lead to new numerical schemes including every significant scales of those complex fluids. Eventually, it may be very adequate to conduct an a posteriori analysis of the models to optimize them.
