Hello,
I am simulating a wavy fin channel with periodic inlet-outlet BC conditions. I am trying to mimic the plot below for the un-slotted wavy fin (shown by the black line): Which shows the periodic component of the pressure (Px) normalized by Kinetic energy: 1.gif From the theory, the periodic pressure can be calculated using: Px(periodic pressure) = P+(DeltaP)*x To do this, I created a custom field function: (P +( periodic-pressure-gradient*x)), I have used the periodic-pressure-gradient that is auto-generated in the report when giving the periodic condition. I plotted these Px results to get: 2.gif As this is the periodic pressure; the end and the start point should be the same as seen in the first chart. I have compared and validated the other results, so I know the model is correct. I am only facing issues with this chart. Is there any other way to get the periodic component of the pressure? |

The pressure if you do nothing in Fluent is the periodic pressure.
