Wind profile

tom

Hi all,

I am using the wind profile in v3.6.1 It works fine! However there is a slight problem in that the profile changes slightly as it moves through the domain (problem with all codes). Now the change isn't a whole lot and i'm being very pedantic about this but i would really like the flow to remain stable.

In the CFX forum a person suggested that: "Maintaining a constant profile can be tricky and a constant problem. Some codes allow a feedback mechanism to perpetuate the flow through the model. What happends is that you specify an inlet condition - your profile, and then at the out let you feed back the outlet flow profile back into the inlet. This constant loop ensures that the result reaches a stable profile for a given inlet condition. This can then be input into the final model for a gived roughness and there should be no change in profile conditions throughout the model."

Can I do this with Phoenics?

Thanks for any help!
