Labyrinth Weir with Air Entrainment
With the increased availability of high performance computing platforms, large scale simulation of complex free surface flows can now include very high meshing density, which delivers a highly accurate representation of the flow. This FLOW-3D HYDRO simulation of a labyrinth weir includes an estimate of air entrainment.

Hydraulic Jump
This FLOW-3D HYDRO simulations shows the development of a hydraulic jump. The top view is a ray-traced rendering of the flow; the bottom view shows a 2D slice of the velocity field. This simulation was postprocessed with FLOW-3D POST.

Tailings Dam Breach
This tailings dam breach was simulated using FLOW-3D HYDRO's tailings model. Variable density layers, including water at the very top, each have their own rheological properties.

Siphon Spillway
In this example of a self-priming siphon spillway modeled in FLOW-3D HYDRO, water flowing through the chute entrains, progressively creating sub-atmospheric conditions in the siphon. In this example, the free surface – TruVOF workspace template as well as a second order momentum advection scheme accurately captures the strongly rotational features of the flow.

Baffle Drop Shaft
FLOW-3D HYDRO can be used to compare drop shaft design elements such as shaft diameter and baffle spacing, which affect the flow velocity, amount of entrained air entrained, and other flow features.
