Final Report on AFOSR (Air Force Office of Scientific Research) Contract F49620-83-C-0064 on Massachusetts Institute of Technology, Cambridge. Volume 1.

Abstract

This document contains papers which summarize work done on this research project. The major results include: 1) Development of renormalization group techniques for large-eddy 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 multi-grid marching method for solution of the parabolized Navier-Stokes equations; 6)A mathematical analysis of boundary conditions for the parabolized compressible Navier-Stokes equations; and 7) The further development of a method to improve numerical solution of singular perturbation problems by use of asymptotic approximations.
