The modeling of turbulent free shear flows is crucial to the simulation of many aerospace applications, yet often receives less attention than the modeling of wall boundary layers. Thus, while turbulence model development in general has proceeded ver

This paper reviews the current state of large-eddy simulation (LES) for nozzle flows and discusses the issues which currently limit its application to simulating realistic noise reducing nozzle systems. LES has been used extensively to compute the fl

High-order methods are quickly becoming popular for turbulent flows as the amount of computer processing power increases. The flux reconstruction (FR) method presents a unifying framework for a wide class of high-order methods including discontinuous
