I’m currently trying to simulate the flow around an impeller inlet. There are two things, that really concern me:
the velocity gets up to >2000 m/s while the initial velocity is about 15 m/s. I really don’t know where these high speeds come from and I have tried other simulations with a similar profile and it does not always happen. I just can’t figure out why it does sometimes!
around the profile as well as the flow channel appears a red frame which I don’t know if it means that there is a velocity oder if it’s just a frame? I hope it does not mean that there is a high speed as the speed should be zero at the wall
I appreciate any help. Thanks a lot!
