We present a subgrid-scale model for the Multi-phase Interstellar medium,Star formation, and Turbulence (MIST) and explore its behaviour inhigh-resolution large-eddy simulations of isolated disc galaxies. MIST followsthe evolution of a clumpy cold and a diffuse warm component of the gas within avolume element which exchange mass and energy via various cooling, heating andmixing processes. The star formation rate is dynamically computed from thestate of the gas in the cold phase. An important feature of MIST is thetreatment of unresolved turbulence in the two phases and its interaction withstar formation and feedback by supernovae. This makes MIST a particularlysuitable model for the interstellar medium in galaxy simulations. We carriedout a suite of simulations varying fundamental parameters of our feedbackimplementation. Several observational properties of galactic star formation arereproduced in our simulations, such as an average star formation efficiency~1%, a typical velocity dispersion around ~10 km/s in star-forming regions, andan almost linear relationship between the column densities of star formationand dense molecular gas.
