Hello there,

I'm running the transient simulation for condensation in the microchannel. The simulation is ok and I got the graph for the local heat flux. But, I want to calculate the time-averaged wall heat flux? Honestly, I don't know exactly how to calculate the time-averaged wall heat flux from the local heat flux. Is there any way to do it in post-processing? Or do I have to calculate it separately?

If you have already your run finished and you have report file for local heat flux: just use third party program or python to do the averaging over time. I assume the local heat flux is vs flow time so make the time average out of it using any integration rule.

thank you for the reply. The local heat flux is vs the position or the length of the microchannel. Have a look:

Okay then you need to create a mean heat flux at each position: you can do that with Fluent Data Sampling. If you do not want to repeat the run: you need to sort it out "outside" of Ansys Fluent.
