Hi,
Discrete Random Walk (DRW) model includes the effect of turbulent dispersion on particle tracks by adding a perturbation or a fluctuating velocity component to every track emanating from the injection locations
For more details, please refer to theory guide: 12.2.2. Turbulent Dispersion of Particles (ansys.com)
