fluent:Few tips to avoid the reversed flow on pressure outlet boundary

2017-01-16  by:CAE仿真在线  来源:互联网

1. Check whether the static (gauge) pressure value at the outlet boundary is set up correctly.

2. If the solution is not initialized with the appropriate flow variables, the *reverse* flow may occur at the starting. However, there are chances that the *reverse* flow will stop after a few iterations once the solution becomes stable.

3. You may want to extend the domain further in downstream direction.
