Hi everyone:

How to get the data of the residence time of fluid (in single phase flow) in the calcualtion domain? The time may be displayed from Display/ Pathline. But how to get the value of time at different locations at the outlet of the domain. I need these numbers for further analysis.

Thanks a lot!

How about to use 'Particle Track', which I use very frequently to check residence time.

The particle should be,

1)small enough, e.g., 1.e-09 meter, and 2) density is similar or very low compared to the gas phase density,

in order to prevent slip between gas phase and particle. That is to say, particle trajectories shoud be nearly identical to those of pathlines, because your purpose is to see pathline not particle track.

In particle track display options, you can have much information about residence time and residence time distribution.

Sincerely, Jinwook
