The Fluid Group is experienced in modelling spillway flows using Computational Fluid Dynamics (CFD).
Spillways need to be able to discharge flood waters to prevent breaches to reservoirs and dams which could endanger lives or property.

A sudden discharge down a spillway chute is a dramatic event which can be accurately simulated with CFD. CFD is a cost effective analysis technique for comparing new designs or confirming an upgrade to an existing structure.

An example of a project the Fluid Grouped work on was the upgrading of the Kennick, Tottiford and Trenchford (KTT) Spillways in Dartmoor National Park when the reservoirs were upgrade from Category B to Category A. The modification works on the spillways included reshaping the overflow weirs, replacing the existing bridges with cast in situ culverts, widening and deepening the spillway channels and providing a suitable stilling basin. Diversion of existing pipe work was also required at all three dams.

The design and geometry of the weirs, culverts and spillways were established by an iterative process using Computation Fluid Dynamic Simulations undertaken by Dr Jim Wicks of the Fluid Group. This required initial geometries to be modelled, the outcomes reviewed to ensure that the flow was safely retained in the critical areas and then the geometries amended and modelled again to help value engineer the design. These simulations also established flow velocity and impact loadings for all parts of the proposed spillways.

An animation of one of those discharge scenarios is shown in the video below.
