Some results of CFD2k simulations:

1. Backward facing step flow with transient start-up phase:
Animation of the transient start-up phase.
Field contour of x-velocities
Averaged solution at steady state conditions with dt_Avg=3msec. Field contour of x-velocities with vectors Transient bahaviour of globally averaged velocities and mass (averaged over whole domain)
Backward facing step Field contour of x-velocities with vectors Transient behaviour

2. Asymmetric double injection at start-up:
Animation of the transient start-up phase. Field contour of static pressure.
When injection starts pressure waves are generated.
Transient bahaviour of globally averaged velocities and mass (averaged over whole domain). A restart was performed after 2.5e-4sec (59. Iteration) 
Pressure waves at start-up mean velocities and total mass

3. Transient flow in a staggered expansion:
Animation: Fluctuating expansion flow (staggered nozzle) Averaged solution with dt_Avg=1.73e-02sec. Field contour of x-velocities with vectors Transient bahaviour (large scale fluctuations) of globally averaged velocities and mass (averaged over whole domain).
