DNS of a non-reacting HIT
This is a very simple DNS computation of a HIT with a constant-properties gas.
The main parameters of the simulation are:
- temporal integration: RK3,
- spatial scheme: 4th order skew symmetric
- no AV.
In this series of computations, the number of cell is increased from 64^3 to 256^3.
DNS of a non-reacting supercritical mixing layer
This simulation is a DNS of a HIT non-reacting supercritical mixing layer with real-gas properties (equation of state, thermodynamic laws and transport laws).
The main parameters of the simulation are:
- temporal integration: RK3,
- spatial scheme: 4th order skew symmetric
- EOS: Soave-Redlich-Kwong.
- Transport laws: Chung et al.
The fields that are displayed are the density (up) which varies from 80 to 800 and the mixness ratio (0 in pure constitutents and 1 for perfect mixness).
