DISPLAY
The problem concerns 2D incompressible, laminar/turbulent
flow over a back-facing step. The case is similar to that
described for library case T103. The main objectives of
it are:
1. Provide comparative test against calculations by stag-
gered algorithm for the case set whether as Cartesian
(CARTES= T, or cylindrical geometry (CARTES= F).
2. Provide test for the use of turbulence model with CCM-
method (LTURB=T). The calculation is performed with
either the Lam-Bremhorst low-Re K-E model (LTWOL=F) or
the 2-layer low-Re K-E model (LTWOL=T), rather than
with the standard high-Re form plus wall functions.
User can switch from the default colocated computational
algorithm (CCM) to the staggered one (STAG) by setting
LCCM = F. While using CCM-method, it is possible to use
higher order convective schemes (see settings at the end
of Q1-file).
A fully developed parabolic laminar flow profile can be
prescribed at the inflow by setting LUNIF = F. Otherwise
inflow is uniform.
