  DISPLAY
  The 1985-version of the two-fluid model of turbulence is here
  used for simulating turbulent combustion in gases. The diffusion
  flux is directly calculated from the normal-to-wall-velocities;
  an additional source for the normal-to-wall momentum equations,
  due to the mean-velocity gradient, is postulated.

  The flame spreads from a flame holder in a stream of pre-mixed
  combustible gas in a duct of constant cross-section.
