Analysis of Three-Dimensional Viscous Internal Flows.
Abstract
A fifteen-month multi-tasked research project was pursued by the present investigators to study complex viscous flows under AFOSR sponsorship between July 1985 and September 1986. The major objective of this study was to require improved understanding of viscous flows and to develop basic computational methods for efficient determination of 2-D/3-D subsonic and incompressible flows. Two major analyses were pursued. These include the Interacting Parabolized Navier-Stokes (IPNS) analysis for steady flows and the full Navier-Stokes (NS) analysis for direct simulation of unsteady flows. The IPNS analysis developed employs no ad hoc artificial dissipation and, in spite of being a density-based formulation, performs well even for very low Mach numbers. The applications considered include 2-D cascades and channels of simple geometry. Keywords: Viscous Flows, Flow separation, Unsteady flows, Interacting equations, Multi Block structured grids, Three dimensional flows.
