Fluid Dynamics
Scientific paper
Recent and ongoing experiments have studied mechanisms that affect the evolution of supernovae, supernova remnants, and related systems. These experiments are designed to be well scaled from astrophysical systems to the laboratory. The experiments and some of the astrophysical systems involve time-dependent flows with very large Reynolds number. In contrast, numerical viscosity limits computer simulations of these phenomena to a Reynolds number of order 1000. Using our own experiments and other work in fluid dynamics as a guide, we will explore the implications for astrophysical systems. The key question is whether the astrophysical systems might evolve into a turbulent state that the computer simulations cannot reproduce. The US DOE and NASA supported this work.
