The Use of Domain Decomposition in Accelerating the Convergence of Quasihyperbolic Systems
Bernard Parent,Jean P. Sislian +1 more
TL;DR: An alternate form of the active-domain method applicable to streamwise separated flows that satisfies the same convergence criterion as the standard pseudo-time-stepping methods, hence resulting in the same converged solution within the tolerance of the user-specified convergence threshold.

The calculations of supersonic viscous flows using the parabolized Navier-Stokes equations
TL;DR: In this paper, a solution of the parabolic Navier-Stokes (PNS) equations for supersonic flows is discussed, and compatibility of the PNS method with the triple-deck theory of Stewartson (1974) is demonstrated.

Development of an iterative PNS code for separated flows
TL;DR: A new iterative parabolized Navier-Stokes (PNS) algorithm is being developed to efficiently compute supersonic viscous flowfields with embedded separated regions that is successfully incorporated into NASA’s upwind PNS (UPS) code.

Multi-level adaptive solutions to boundary-value problems
TL;DR: In this paper, the boundary value problem is discretized on several grids (or finite-element spaces) of widely different mesh sizes, and interactions between these levels enable us to solve the possibly nonlinear system of n discrete equations in 0(n) operations (40n additions and shifts for Poisson problems); and conveniently adapt the discretization (the local mesh size, local order of approximation, etc.) to the evolving solution in a nearly optimal way, obtaining "°°-order" approximations and low n, even when singularities are present.

Calculation of supersonic viscous flow over delta wings with sharp subsonic leading edges
TL;DR: In this article, two complementary procedures were developed to calculate the viscous supersonic flow over conical shapes at large angles of attack, with application to cones and delta wings, respectively.
Solutions for incompressible separated boundary layers including viscous-inviscid interaction
TL;DR: In this article, numerical solutions for the laminar and turbulent boundary-layer equations for incompressible flows with separation and reattachment are presented, where the separation angularity is avoided by using an inverse technique in which the displacement thickness is prescribed and the pressure is deduced from the resulting solution.
