“Piz Daint” to study 3D compressible flows

We are using “Piz Daint” to compute statistical solutions for compressible fluids. These mathematical objects are probability measures in infinite dimensions that model all possible multipoint correlations of the flow and describe uncertainty propagation in turbulent fluid flows. We run an optimized, high-resoution, finite volume code (ALSVINN) on “Piz Daint” to compute statistical observables such as mean, variance, structure functions, etc., for three-dimensional compressible turbulent flow to discover interesting qualitative and quantitative properties of these solutions.
