The Navier-Stokes (NS) equations are an excellent mathematical model for turbulent flows. However, direct simulations at high Reynolds numbers are not feasible yet because the non-linear convective term produces far too many scales of motion. Hence, in the foreseeable future, numerical simulations of turbulent flows will have to resort to small-scale models. In this regard, large-eddy simulation (LES) equations result from filtering the NS equations in space. The effect of the under-resolved scales is then given by the subgrid stress (SGS) tensor that depends on both the filtered and the unfiltered velocity. Then, the famous closure problem in LES basically consists of approximating the SGS tensor with a tensor in terms of the (resolved) filtered velocity. In this way, the dynamical complexity of the NS equations is significantly reduced, resulting in a new set of PDE that are more amenable to being numerically solved on a coarse mesh. Over the past decades, the field of LES has drastically evolved together with the never-ending growth of computational capacity, gaining interest for a wider and wider range of applications. In this context, the objective of this Special Issue of Energies is to bring together people working on advanced, cutting-edge methods for the LES of turbulent flows but also on applications where LES techniques are allowing one to explore new frontiers. The scope includes, but is not limited to the following:
- LES fundamentals;
- Numerical methods for LES;
- Wall-modeling techniques;
- Hybrid RANS-LES methods;
- Heat and mass transfer problems;
- Multiphase flows;
- Environmental and geophysical applications;
- Industrial applications.
