comment How do you add temperatures?
@Aziraphale The given table is in $K$, so perfectly fine imo :)

Awesome extension. Thanks!

Well, the question is, how break up of the vortex rings into smaller vortex rings happens. At that point, you already lost the interface, so there is no surface tension. Right?

comment FVM discretisation
Furthermore, your title says FVM while the text says FDM. There is not really a significant difference in 1D, but you have to be precise, especially when it comes to boundary conditions. :)

Can surface tension play a large role if the two fluids mix?

But I fail to see how the transition to turbulence is trigger. For smoke rings I see the point of buoyancy driven light/hot smoke hitting the stagnant cooled down smoke. But here I do not see something similar.

Did you estimate the Reynolds number? I would guess it is more of a laminar process, rather than turbulence.

The linked question reads "I could ask this on the physics site however I am hoping for a relatively simple answer."

Are you sure? I'm pretty sure I once saw a video with a counter-rotating wheel, such that the net angular momentum is zero. I think there are more effects playing a role
