Turbulence is a fundamental process that drives mixing and energy redistribution across a wide range of astrophysical systems. For warm (T ≈ 10^4K) plasma, the material is partially-ionised, consisting of both ionised and neutral species. The interactions between ionised and neutral species are thought to play a key role in heating (or cooling) of partially-ionised plasmas. Here mixing is studied in a two-fluid partially-ionised plasma undergoing the shear-driven Kelvin-Helmholtz instability to evaluate the thermal processes within the mixing layer. 2D numerical simulations are performed using the open-source (PIP) code that solves for a two-fluid plasma consisting of a charge-neutral plasma and multiple excited states of neutral hydrogen.
