Star formation in galaxies causes supernova explosions, and thereby both, turbulence and, if strong enough, winds or galactic fountains. High star formation rates, outflow features and turbulence are prime characteristics for high redshift galaxies. Here, we propose 3D hydrodynamics simulations to address the problem, in particular with the aim to find a logical connection between star formation, turbulence and outflow characteristics. As methodological improvements over previous work, we'd like to use a grid-based approach with realistic initial conditions from a cosmological simulation, and account for radiative transfer effects. We will produce realistic models for the galaxy-halo interaction, and clarify, if continuous accretion can occur simultaneously with strong outflow features.
