DISPLAY
This case concerns axisymmetric incompressible laminar/
turbulent flow in the expanding pipe. The flow rotates,
with linear swirling velocity profile at the inlet. The
flow exhibits recirculation not only behind the step at
the pipe wall, but in the region on the pipe axis.
Calculations of the turbulent flow (LTURB=T) could be
made with low-Re extensions of whether standard K-E model
(LOWKE=T) or Chen-Kim K-E model (LCHEK=T).
Computational domain is built from 2 blocks with grid
sizes NX1,NY1,NZ1 and NX2,NY2,NZ2 respectively. The grid
for the after step region can be IFCZ times finer in the
Z-direction as the grid at the top.
