Abstract:

Particulate matter transported by stormwater is a hetero-disperse mixture of particles that results in significant challenges to designing effective measures for pollution control. Hydrodynamic separators are an option for removal of coarse particles. A screened HS includes gravity sedimentation, size exclusion and inertial separation as mechanisms of particle separation. Particle removal was modeled with a 3-D computational fluid dynamics (CFD) approach, across the range of operating flow rates. A standard RANS model was used to model turbulent flow and a discrete averaging technique was applied to track particles. Results from the model were in good agreement with experimental measurements and provided further insight into the dependence of removal within the different regions of the screened HS as function of particle diameter.
