Higher velocity outlet -- CFD Online Discussion Forums

Matiwww New Member Yes Join Date: Feb 2021 Posts: 4 Rep Power: 5	Why is my outlet velocity is high and my tke and tdr is high even its not normalized? I am using star CCM+ to simulate a tube. I used k-e model and implicit unsteady with good mesh, lower relaxation factor of solver and not normalized residuals. My inlets are diameter 1.6 and 6 mm mm and my outlet is 14mm. And my boundary at inlet has 0.1 m/s. Its an ideal gas modell. My outlet wall jumps upto 600m/s when i see it in scalar view but when i plott velocity at just the outlet boundary region then it shows 50-60 m/s. Should i ignore the wall velocities?
