Abstract : This document contains papers which summarize work done on this research project. The major results include: 1) Development of renormalization group techniques for largeeddy simulations of turbulent flows; 2) The first direct numerical simulation of turbulent spots in channel and boundary layer flows; 3) The further development of spectral methods for turbulence simulations; 4) The identification of secondary instability modes in free shear layers; 5) The development of an efficient multigrid marching method for solution of the parabolized NavierStokes equations; 6)A mathematical analysis of boundary conditions for the parabolized compressible NavierStokes equations; and 7) The further development of a method to improve numerical solution of singular perturbation problems by use of asymptotic approximations.
