33rd Discrete Simulation of Fluid Dynamics Conference

The International Conference on Discrete Simulation of Fluid Dynamics (DSFD) has, since 1986, been the primary forum for advances in fluid dynamics based on kinetic theory and statistical mechanics. The 33rd edition, held at Eidgenössische Technische Hochschule (ETH) Zurich, in July 2024, gathered researchers from around the world to present recent progress in discrete and mesoscopic approaches. This special issue of Physics of Fluids features 24 peer-reviewed contributions selected from the meeting. The papers cover methodological developments in lattice Boltzmann and smoothed particle hydrodynamics, advances in efficiency and scalability on modern computing platforms, and applications ranging from multiphase and porous media flows to fluid–structure interactions, granular systems, and bio-inspired dynamics. Together, these works illustrate the continued vitality of DSFD research, highlighting discrete kinetic methods as powerful and evolving tools for modeling complex fluid phenomena.
