That sounds reasonable: vortex cores are known to wander around, Prof Nick Syred did a lot of work in the field.Â
We're happy that the single phase model is unstable and inherently transient. Given multiphase tends to be less stable (and far more transient) would you expect it to be easier or harder to get a good result? Also, with a vapour/gas in the domain where do you think it'll collect, and then go?Â
