Best Practice Advice for the UFR

Key Physics

The key physics to be captured in this UFR is the self-similar behaviour of a spreading axisymmetric buoyant plume.

Numerical Modelling Issues

  • The flow can be treated as axisymmetric.
  • For a grid-independent resolution of the George et al. [3] plume, at least (40 × 100) grid nodes should be used in the (radial × axial) directions. At least 10 nodes should be used radially to resolve the plume source.
  • Discretization schemes should be at least second-order accurate.
  • For further advice on boundary conditions, see Test Case
