Dataset description
Forced Isotropic Turbulence Dataset on 81923 Grid:
Simulation data provenance: Georgia Tech DNS code (see README-isotropic8192 for more details).
- Direct numerical simulation (DNS) using 81923 nodes.
- Navier-Stokes is solved using pseudo-spectral method.
- Time integration uses second-order Runge-Kutta.
- The simulation is de-aliased using phase-shifting and truncation.
- Energy is injected by keeping the energy density in the lowest wavenumber modes prescribed following the approach of Donzis & Yeung.
- After the simulation has reached a statistical stationary state, a frame of data, which includes the 3 components of the velocity vector and the pressure, are generated and written in files that can be accessed directly by the database (FileDB system).
- Domain: 2π × 2π × 2π
- Grid: 81923
- Number of snapshots available: 6
- Taylor-scale Reynolds number Reλ ~ 1200-1300 for snapshots 0-4, and Reλ ~ 610 for snapshot 5
- Viscosity, dissipation, RMS velocity, and Kolmogorov scale: see README-isotropic8192
- GetPosition is not implemented for this dataset.
