Overflows and Launders

This example illustrates the flow of water through an overflow system.

Applications

Case Study

The free surface multiphase model has a range of industrial applications. Typical simulations include:

  • flow of segregated liquids and gases in vessels
  • slug flow
  • trapped gases
  • jet breakup
  • motion of large bubbles in a liquid
  • motion of liquid after a dam break

In this project, the simulation was used to accurately calculate the capacity of the combined launder and overflow system at Rusal Aughinsh.

The results of this simulation were used to determine the maximum capacity of the system for a safety assessment and to determine which section was the limiting factor.

Other effects such as the influence of a sealed overflow chamber compared to a vented designs were also quantified.
