Sewer hydraulics, especially those that combine both pressurized and free-surface hydraulic conditions, represent an application area that is ideally suited to FLOW-3D‘s modeling strengths. The combined sewer overflow (CSO) problem that exists in thousands of older American cities is a classic sewer design example where there is a need for CFD approaches that allow for seamless transitions between pressurized and free-surface hydraulic controls. In addition to accurately capturing hydraulic jumps, FLOW-3D simultaneously solves for air bubble entrapment and pressurization effects.
Additional common applications include municipal drop shaft vortex dynamics, air entrainment and air-driven bulking modeling, and related wet tunnel modeling applications.
