mass flow averaged temperature

Hr_kules · February 15, 2023, 04:33

Hi,

how does one compute the mass flow averaged temperature with postProcess utilities?

I would like to use it to define a reference temperature for heat transfer coeffcient computation.

Hello Nico,

I guess you could use the surfaceFeldValue function object to compute the temperature average, using phi as weightField.

Depending on the version you are using:

ESI-OpenCFD: https://www.openfoam.com/documentati...ieldValue.html
foundation: https://github.com/OpenFOAM/OpenFOAM...ceFieldValue.H

Hope this helps,
Yann
