JMBC Contact Groups
Multiphase Flow
The objective of the Contactgroup Multiphase Flow is to stimulate interaction and collaboration between researchers, developers, and users in the area of multiphase flow from universities, institutes and industries. This is done through organizing regular meetings (once or twice per year) aimed at getting to know each other’s activities and to learn about developments and applications of multiphase flow technology. This will provide a good forum to identify the needs of the users and to bring to the attention new possibilities for applying multiphase flow research results. Industry, a research institute or a university in turn act as host of the meetings. The program consists of a series of lectures on a specific theme and a visit of some of the local multiphase flow facilities. Examples of themes covered are: dynamic multiphase flows, multiphase flows with surface-active agents, multiphase flow measurements and innovation with multiphase flow. On Thursday 12th May 2011 a one-day meeting was held at Deltares in Delft. The theme of that day was "Multiphase Flow and Applications in Civil Engineering".

Computational Fluid Dynamics (CFD)
The purpose of the contactgroup CFD is to give CFD-researchers and users of CFD in universities, laboratories and industries in The Netherlands and Belgium the opportunity to get to know each other and to get acquainted with each other’s work. In 2011 no meeting was arranged.

Combustion
The JMBC has groups active in combustion research at the universities of Delft, Eindhoven, Groningen, and Twente. The contactgroup combustion is an informal network between these groups. The groups play an important role in the organization of the symposia of the Dutch section of the Combustion Institute, which is part of the international Combustion Institute, an international forum for scientific combustion research. These groups also have formed the STW-platform ‘Clean and Efficient Combustion’ to enhance the mutual collaboration between the different groups and to interest more industrial parties for the fundamental research on combustion.The COMBURA symposium was organized for the 10th time. It took place in Ede-Wageningen on October 10 and 11. This symposium is the major annual event in The Netherlands for exchange of information on combustion research and its applications. It is a joint initiative of the Technology Foundation STW, the Nederlandse Vlam Vereniging NVV (Dutch section of the International Flame Research Foundation IFRF) and the Dutch section of the Combustion Institute. The first day was devoted to the eight research projects within the STW program on Clean Combustion Concepts (CCC), all of which are executed by research groups of the JM Burgers Centre. On the second day a keynote lectures were presented by Dr. Rick Harwig (TU/e) on "Preparing for the energy transition" and by Prof. Dr. Ing. Hennig Bockhorn (University Karlsruhe) on "Computational combustion. Useful tools or useless toys". Sessions were held on "Future fuels", "Industrial research", "Numerical modeling" and "Engines and Gas Turbines".

Lattice-Boltzmann Techniques
The JMBC contact group on "Lattice-Boltzmann techniques" was first established in 2002. The Lattice-Boltzmann schemes can be seen both as flexible and efficient solvers for macroscopic fluid equations or as particle-based simulation techniques which make close contact with the kinetic theory of gases. It is this last feature that allowed, in recent years, the partial disclosing of the huge potential of the method. The Lattice Boltzmann method has demonstrated great accuracy and performance in dealing with multiphase and multicomponent flows, from laminar to turbulent, in presence of simple or complex boundary conditions. In the past the contact group has also been involved in organizing educational and research events including a Lorentz Center workshop on "Multiscale fluid dynamics with the Lattice Boltzmann method" held in 2011.

Turbulence
The objective of the contactgroup turbulence is to organize meetings between researchers of the J.M. Burgers Centre active in the field of turbulence. The purpose of these meetings is give the AIO/OIO’s and other university researchers the opportunity to present their research results in an informal atmosphere and at the same time to promote a discussion on these results. The meetings also strengthen the contact between the researchers of the J.M. Burgers Centre and allows exchange of results and experience. Activities in 2009 : organisation of the Turbulence Course.

Experimental Techniques
The Contact Group Experimental Techniques forms a platform where experiments and experimental techniques can be discussed and evaluated. The main function of the contact group is to organize meetings in which the practice of experimenting can be discussed. An important contribution of the contact group is the organization of the JMBC course on Experimental Techniques in Fluid Mechanics. The course is very popular among the JMBC members as it gives a broad overview of advanced experimental techniques commonly used in fluid mechanics laboratories. The next course will be held 26-29 April 2010 at the University of Twente.

Biological Fluid Mechanics
More and more research is conducted at the border between biology and fluid mechanics. This happens within many disciplines, from physiology (e.g. the interaction between blood flow and vessel walls) to aerodynamics (e.g. flapping flight). However, all deal with the interaction between fluids and a complex, changing geometry. One of the main challenges is to bridge the gaps between physics (esp. fluid mechanics) and medical and health sciences. To stimulate this relatively young field of research and bring together researchers, a new contact group was started in 2006. While the contactgroup is formally a part of the J.M. Burgerscentrum, the participation from researchers from non-affiliated universities, medical centers and institutes is encouraged. Recent activities include mini-symposia in Wageningen (Experimental Zoology Group) and Eindhoven (in combination with the JMBC course on Bio-fluid Mechanics). The Bio-Fluid Mechanics course (March 2009: about 40 participants) was jointly supported by the JM Burgers Centre and the ERCOFTAC organization by advertising the course amongst their members, via the website and by some financial means.Topics included: a recap of basics of fluid mechanics, external flows (swimming and flying, interaction of plankton and turbulence), internal flows (microcirculation, hemodynamics in large arteries, flow in flexible tubes, respiratory system, etc.). Examples of relevant experimental techniques, as well as simulation techniques were discussed. Finally, members of the contactgroup are active in the definition of a new FOM-program in the bio-fluid mechanics field.

Microfluidics
The contact group "Microfluidics" was established in 2005 with a first meeting in Delft. The purpose of the contact group is to bring together students and postdocs interested in fluid dynamic aspects of microfluidics and give them a forum for presenting their results and exchanging ideas. Topics of interest include wetting and capillarity-driven flows, two-phase flow, drop generation, emulsification, contact line dynamics, flow visualization and measurement techniques. Members of the contact group organize the JMBC course "Capillarity-driven flows in microfluidics", which was first given in 2009 and repeated in 2011. The date of the next meeting of the contact group (spring 2012) will be announced shortly by email to all members of the contact group.
