Flow Maldistribution
I need to quantify flow maldistribution in a vertical cylindrical geometry at a certain plane within the cylinder. I am interested in calculating standard deviation in vel. magnitude at a certain plane. How do i do this in fluent ?. Is there a way where in I can ask fluent to report vel. mag values at all nodes located at a certain plane
thanks in advance |
Re: Flow Maldistribution
I'm not sure if Fluent has this capability- I would normally write out the plane profiles of interest (File>Write>Profile) and then analyse the data in a spreadsheet package.

Re: Flow Maldistribution
I'd do the following:
1. Define the surface I'm interesting in as an iso-surface of a constant grid-coordinate. 2. Use the surface-average function to compute the average velocity on that that surface. 3. Define a custom-field-function to compute the standard-deviation. 4. Use the surface-integral function to integrate up the custom-field-function defined in 3. |
