Case description


Boundary conditions

A precursor boundaryFoam calculation is used to set the inlet flow conditions onto which turbulent content is superimposed using the turbulentDFSEMInlet velocity condition.

Common fields

  • \( U \) 1 m/s
  • \( h \) 1 m
  • \( \nu \) 2.5e-5 m2/s

Velocity: U

The following images show examples of the instantaneous- and mean-velocity predictions

Profiles at a series of x/h positions are presented in the following images, where the predictions are compared against the experimental data of Martinuzzi and Tropea [49]
