“…However, it was recently proven that numerical errors -notably those induced by the equilibriumare at the origin of the latter rotational problem in-stead of the lattice itself 44 . This is in agreement with the fact that several commercial solvers (e.g., Power-FLOW and ProLB) rely on D3Q19 formulations -with regularized/filtered collision models whose equilibria include high-order velocity terms-without suffering from such anistropic issues [45][46][47][48][49] .…”

In a recent work [A. De Rosis, R. Huang, and C. Coreixas, "Universal formulation of central-moments-based lattice Boltzmann method with external forcing for the simulation of multiphysics phenomena", Phys. Fluids 31, 117102 (2019)], a multiple-relaxation-time lattice Boltzmann method (LBM) has been proposed by means of the D3Q27 discretization, where the collision stage is performed in the space of central moments (CMs). These quantities relax towards an elegant Galilean invariant equilibrium, and can also include the effect of external accelerations. Here, we investigate the possibility to adopt a coarser lattice composed of 19 discrete velocities only. The consequences of such a choice are evaluated in terms of accuracy and stability through multiphysics benchmark problems based on single-, multi-phase and magnetohydrodynamics flow simulations. In the end, it is shown that the reduction from 27 to 19 discrete velocities have only little impact on the accuracy and stability of the CM-LBM for moderate Reynolds number flows in the weakly compressible regime.

“…AMR on cubic volumetric elements also underpins the developments in lattice Boltzmann method (LBM) to low-Mach aerodynamics and aeroacoustics, with unmatched meshing capabilities for complex configurations. While the progress in the application of LBM to aeroacoustics is impressive [22,23], its extension to higher Mach number flows and treatment of multi-physics phenomena remain subjects of on-going research, including jet noise [24,25].…”

In the last decade, many research groups have reported predictions of jet noise using high-fidelity large-eddy simulations (LES) of the turbulent jet flow and these methods are beginning to be used more broadly. A brief overview of the publications since the review by Bodony & Lele (2008, AIAA J. 56 , 346–380) is undertaken to assess the progress and overall contributions of LES towards a better understanding of jet noise. In particular, we stress the meshing, numerical and modelling advances which enable detailed geometric representation of nozzle shape variations intended to impact the noise radiation, and sufficiently accurate capturing of the turbulent boundary layer at the nozzle exit. Examples of how LES is currently being used to complement experiments for challenging conditions (such as highly heated pressure-mismatched jets with afterburners) and guide jet modelling efforts are highlighted. Some of the physical insights gained from these numerical studies are discussed, in particular on crackle, screech and shock-associated noise, impingement tones, acoustic analogy models, wavepackets dynamics and resonant acoustic waves within the jet core. We close with some perspectives on the remaining challenges and upcoming opportunities for future applications. This article is part of the theme issue ‘Frontiers of aeroacoustics research: theory, computation and experiment’.

“…Interesting result have been obtained also for subsonic jet noise computations. 17,18,19 Lew et al 18,19 successfully simulate the noise generated for low and high subsonic jet including the nozzle geometry in the computational domain. The LBM turns out to be computationally more efficient with respect to the traditional NS-LES for low Mach number flow.…”

Let us note, that Lew et al 18,19 in his jet simulations avoid the use of NRBC by damping the outgoing disturbances with a very coarse grid near the boundaries. Requiring a big computational domain with respect to the smaller physical domain of interest, this strategy can be computationally demanding.…”

The lattice Boltzmann method (LBM) is emerging as a powerful engineering tool for aeroacoustic computations. However, the LBM has been shown to present accuracy and stability issues in the medium-low Mach number range, which is of interest for aeroacoustic applications. Several solutions have been proposed but are often too computationally expensive, do not retain the simplicity and the advantages typical of the LBM, or are not described well enough to be usable by the community due to proprietary software policies. An original regularized collision operator is proposed, based on the expansion of Hermite polynomials, that greatly improves the accuracy and stability of the LBM without significantly altering its algorithm. The regularized LBM can be easily coupled with both non-reflective boundary conditions and a multi-level grid strategy, essential ingredients for aeroacoustic simulations. Excellent agreement was found between this approach and both experimental and numerical data on two different benchmarks: the laminar, unsteady flow past a 2D cylinder and the 3D turbulent jet. Finally, most of the aeroacoustic computations with LBM have been done with commercial software, while here the entire theoretical framework is implemented using an open source library (PALABOS).
