Finding Average Temperature of a Contour

imanfitri1 · March 5, 2021, 12:24

Hi everyone,
I have a problem of trying to find the average value of a contour in ANSYS CFD-Post. I am able to display the temperature over a plane for the outlet of my heat exchanger (shown in the link)

I am trying to figure out how to find its average temperature for the same plane in the form of a plot so I can determine the average temperature difference from the rest of the planes within the drawing.

Use a CEL expression to get the average temperature:
TaveOutlet = massFlowAve(T)@Outlet
you can then use this in subsequent expressions, then create Variables for temperature difference using another expression TdiffFromOutlet = (T - TaveOutlet).
Make a variable based off this expression, which can then be plotted.
