Detailed Description

wall functions descriptor.

Members of this wall functions descriptor are publicly accessible, to allow for concise syntax, as it is expected to be used in many places.

Field Documentation

ideuch

wall functions

  • 0: one scale of friction velocities
  • 1: two scale of friction velocities
  • 2: scalable wall functions
ilogpo

wall functions with

  • 0: a power lay (deprecated)
  • 1: a log lay
iwallt

exchange coefficient correlation

  • 0: not use by default
  • 1: exchange coefficient computed with a correlation
ypluli

limit value of $y^+$ for the viscous sublayer

ypluli depends on the chosen wall function: it is initialised to 10.88 for the scalable wall function (ideuch=2), otherwise it is initialised to $1/\kappa\approx 2,38$. In LES, ypluli is taken by default to be 10.88. Always useful.
