Description of the flow problem
-
length of channel before/in/after the lower inlet/total:
2.3/0.2/10.3/12.8
-
height of channel/lower pipe : 1.0/1.0
-
inflow b.c.'s: constant with velocity 1 at the left side
-
inflow b.c.'s: constant with velocity 20 at the lower side
-
outflow b.c.'s: natural "do nothing" b.c.'s at the
right side
-
other b.c.'s: zero velocity at fixed walls
-
initial condition at t=0: starting from fully developed
-
viscosity parameter: 1/nu=100,000
