What is the effect of particle diameter on turbulent dispersion in a DPM simulation?
The discrete random walk (DRW) model includes the effect of turbulent dispersion on particle tracks by adding a perturbation or fluctuating velocity component to every track emanating from the injection locations. The number of tries controls the number of "sub" tracks to be estimated from every injection point. Each of these "sub" tracks will typically follow a different path perturbed about the mean path.
