Mesoscopic methods encompass a group of numerical approaches that can be jointly described as coarse-grained approximations of the behavior of matter. They provide a simpler description than molecular dynamics (microscopic method) but (possibly) recovering more information than macroscopic continuum approaches. These methods include: Lattice Gas Automata (LGA), Smoothed-Particle Hydrodynamic (SPH), Dissipative Particle Dynamics (DPD), Discrete Velocity Methods (DVM), Direct Simulation Monte Carlo (DSMC), Method of Moments (MoM), linear and non-linear Reduction Order Methods (ROM), Lattice Boltzmann Methods (LBM), Gas Kinetic Schemes (GKS) or Relaxation Schemes, among others. The target macroscopic equations in the continuum limit are transport equations of mass, momentum, energy, chemical species, electricity or magnetism; being the actual equation solved dependent on the particular mesoscopic method (e.g. Newton’s second law, Boltzmann equation or Fokker-Plank equation).


Benefits provided by mesoscopic methods for actual-industrial problems are:


  1.  Multiphysics capabilities, as several transport phenomena, both close and far from thermodynamic equilibrium, can be solved with the same numerical approach. 
  2. Access to multiscale information, especially for those mesoscopic methods based on Kinetic Theory or on Statistical Mechanics (e.g. LBM or DVM). 
  3. Easy handling of complex geometries due to several mesh-free approaches or ways to deal with immersed boundary methods. And 
  4. computational efficiency through algorithms designed for modern HPC architectures, such as GPU’s. Each mesoscopic method has at least one of these four distinctive advantages.


This minisymposium aims to give an overview of the present application of mesoscopic method within several industrial sectors, i.e. energy, oil, pharmaceutical, chemical and transport; providing the opportunity to gain insight into how to exploit the aforementioned distinguish features of mesoscopic methods to provide innovative solutions of real-life problems.
