Re=14000, Mach=0.2, non-structured mesh of 9*10^{9} nodes, high-order vertex-centered scheme.
DNS case performed on Lomonosov supercomputer of MSU using 1600 CPUs.

Re=2500, Mach=0.1, non-structured mesh of 1500000 nodes, high-order vertex-centered scheme.
This is a preliminary test case for a new large-scale DNS problem. It was performed on MVS 100000 supercomputer of MSC RAS using 200 CPUs.

Re=1000, Mach=0.4, non-structured mesh of 800000 nodes, high-order vertex-centered scheme.
This is a preliminary test case for a new large-scale DNS problem. It was performed on MVS 100000 supercomputer of MSC RAS using 120 CPUs.

2D cases, non-structured meshes up to 800000 nodes, performed on RSC4 cluster in 2005.
The flow with Mach number M=0.4 is injected from the left with or without flat acoustic waves.
Research covers mixing layer whistle, interaction with input waves,
turbulence inside of the resonator, multiple resonators interaction, etc.

3D cases, non-structured meshes up to 1300000 nodes, performed in IMM RAS by A. Gorobets, I. Abalakin
and T. Kozubskaya on MVS 100000 supercomputer of JSC RAS, 2007.
A flat low-frequency acoustic wave enters (from the left) to a circular impedance tube with a resonator chamber.
Phenomena of transition of the acoustic energy into energy of turbulent motion was investigated.
Turbulent flow appears when the wave interacts with the resonator's mouth.
