[讨论]outflow B.C.

wtyeh

Hi:
My model is a simple geometry like a pipe.
I used FLUENT to simulate the flow field.
But the velocity jumped near the outlet.
I tried the pressure outlet agian.
The velocity didn';t jump near the outlet.
The flow was fully develop. But the velocity jumped in the outflow B.C.
Anyone could tell me why the outflow B.C. would have velocity jump??
Thanks a lot!

入口段的长度这么短就达到充分发展了？你的管径和雷诺数是多大？
