Abstract
The project comprises general properties of supersonic turbulence aswell as its significance to turbulence-regulated star formation in thecontext of galaxy evolution. In the first phase of the project, weintend to run numerical simulations of supersonic turbulence inself-gravitating gas employing both continuous and discrete schemes ofstochastic forcing. This phase is a continuation of an ongoing DEISAproject, in which the applicability of adaptive mesh refinement inturbulence simulations is studied. In the second phase, the resultsobtained from a statistical analysis of the various turbulencesimulations will yield the input for a probabilistic model of starformation to be applied in simulations of galaxy evolution withdifferent degrees of feedback between unresolved stellar processes andturbulence energy. We are going to carry out the computations usingthe open source code Enzo in combination with the FEARLESS (FluidmEchanics with Adaptively Refined Large-Eddy SimulationS) methodologythat is presently being developed by our research team.
