Visualization of 3D liquid-vapor interface in Fluent

vjo · February 23, 2023, 04:35

Hello and greetings to all.
I am working on two phase flow of water in a heated microchannel. I am relatively new to Ansys and having trouble to show liquid-vapour interface with tempertaure contours in Ansys Post. I am posting a picture for a reference figure i saw in an research paper depicting bubbles in a microchannel.

Can anyone please explain how to obtain these figures in Ansys Fluent??

The temperature contours should be pretty simple - you can create a contour figure in Fluent (or CFD-post) for the temperature once you have your results. For a figure like this, you will want to specify which surfaces to plot the results on (by selecting each wall you want the temperatures to show on, for example).

I'm not 100% sure about the two-phase flow regime, though. One thing you can try is making an isosurface plot, where you specify a specific value to plot - this may help you plot only one specific phase. However, i'm not certain how to get two plots to overlay on one another - I imagine this is easier done in CFD-post than in Fluent's post-processing.

Perhaps someone with more experience than me may be able to expand on this.
