DES (Detached Eddy Simulation)

The length scale in the destruction term of the SA turbulence model is modified:

  • Instead of the wall normal distance, the length scale is now the minimum of the wall normal distance and a length parameter

Boundary layer solver

This page describes some parameters used to measure the properties of boundary layers. Consider a stationary body with a turbulent flow moving around it, like the semi-infinite flat plate with air flowing over the top of the plate. …

Plane Channel Simulation

    • Channel flow configuration with streamwise and spanwise periodic boundaries
    • Domain size: 8H × 3H × 2H where H is half channel height. Smallest wall-normal spacing is 2 × 10-3 H
    • Grid size sufficient for a well resolved

Synthetic turbulence generation

With respect to STG, the calculation of spatial modes required for synthetic turbulence has been validated and the perturbations are calculated ( v’ in the Shur et al.). Following figures are attached:

Blue portion in figure(b) is the wave numbers …
