The 26th International Conference on Discrete Simulation of Fluid Dynamics (DSFD) was organized and hosted by the Helmholtz Institute Erlangen-Nürnberg for Renewable Energy (Forschungszentrum Jülich) and the Friedrich-Alexander-Universität Erlangen-Nürnberg (http://www.dsfd.org). It took place in the center of Erlangen at “Kreuz+Quer – Haus der Kirche” and attracted more than 150 researchers from more than 19 different countries. The program featured 9 internationally highly reputed keynote speakers, 101 contributed presentations, 20 poster contributions and two tutorial sessions.
The DSFD series originated in 1986 and is an international established forum for all researchers working with kinetic and stochastic based numerical models for fluid dynamics, e.g., lattice Boltzmann schemes, dissipative particle dynamics, smoothed-particle hydrodynamics, direct simulation Monte Carlo, molecular dynamics, quantum Monte Carlo methods, multi-particle collision dynamics and hybrid methods. In the spirit of the preceding conferences, this year’s meeting covered a wide range of topics - from liquid films and microfluidics to thermal problems, colloids and suspensions, electrokinetics, as well as relativistic flows, industrial applications and of course numerical analysis and general model development.
The invited keynote lectures focused on complex flow applications and combined high level contributions on experimental, theoretical and numerical work from a wide range of scientific disciplines. G. Gompper (Forschungszentrum Jülich) presented models of swimming bacteria to study the collective dynamics in active colloids. H.J. Herrmann (ETH Zürich) spoke about particle-laden flows in porous media, including numerical studies of deposition and erosion in porous structures. The collective dynamics of social insects was studied by L. Mahadevan (Harvard University), while T. Pöschel (FAU Erlangen-Nürnberg) referred to so-called “vibrots” as a well-defined experimental system to test granular theories. D. Quéré (ESPCI Paris) discussed the nanostructure of anti-fogging materials that minimize water adhesion. Urban physics simulations were discussed by P. Sagaut (M2P2 Marseille), who showed that lattice Boltzmann models can be used to predict flow in realistic full scale scenarios resembling the architecture of cities. H. Stark (TU Berlin) presented studies of colloids in microfluidic flows based on multi-particle collision dynamics and lattice Boltzmann methods. Another hot topic was lattice Boltzmann methods for multiphase flows with high density ratio. H. Kusumaatmaja (University of Durham) presented a ternary model including entropic stabilization for high Weber and high Reynolds numbers. Last but not least, T. Lee (City College of New York) discussed a pressure-velocity formulation of the lattice Boltzmann equation for immiscible incompressible flows.
To give the participants the chance to expand their knowledge even further, a tutorial session on entropic lattice Boltzmann schemes for high Reynolds numbers was held by I. Karlin (ETH Zürich) and S. Ansumali (Jawaharial Nehru Centre for Advanced Scientific Research India). This lecture was accompanied by a second tutorial by S. Succi (IAC-CNR Rome) on the history of the lattice Boltzmann method, as well as future perspectives. Furthermore, numerous high-quality oral contributions and posters guaranteed an exciting meeting with 5 days full of scientific discussion.
By tradition, the conference also featured a social program: Most importantly, a conference dinner at the restaurant Bayerischer Hof in Erlangen that was very well attended. Additionally, on Wednesday afternoon the participants were offered either a guided tour through the historic center of Nürnberg, the beer-cellars in Erlangen, or a visit of the Teufelshöhle and Pottenstein in Franconian Switzerland.
The response to the conference was overwhelmingly positive and the local organizers thank all contributors to the scientific program. Financial support from the “Deutsche Forschungsgemeinschaft (DFG)” and the Cluster of Excellence “Engineering of Advanced Materials” (EAM) is highly acknowledged.
DSFD 2018 - the succeeding event in the series - will take place in June 2018 in Worcester, Massachusetts, USA.
