DISPLAY
The problem concerns the steady fully-developed turbulent flow
of a Bingham-plastic non-Newtonian fluid. This type of fluid
remains rigid when the shearing stress is less than the yield
stress tauy and flows somewhat like a Newtonian fluid when the
shearing stress exceeds tauy. The turbulence is simulated by the
high-Reynolds number k-e model plus wall functions, although the
user might like to try the low-Reynolds-number k-e model because
the laminar viscosity varies rapidly in the near-wall layer due
to the rapid increase in the rate of strain as the wall is
approached.
