yeah, plasma’s all about that hot, ionized mess of particles. When you’re running a CFD for jets, you’re really looking at how the electrons, ions and neutrals exchange energy, plus the magnetic field if you’ve got one. One quick thing: make sure you’re using a non‑equilibrium model – the electrons heat up way faster than the ions, so a single temperature isn’t enough. Also watch the ionization fraction; if it drops too low, you’ll miss the glow and the pressure forces. And don’t forget the radiative losses – in a high‑temperature jet, they can dominate the energy budget. Fix those three and your debug marathon will get a lot easier.
