High Order Accuracy Computational Methods in Aerodynamics Using Parallel Architectures.

Abstract

In this research we presented the development and application of spectral shock capturing techniques as well as ENO finite difference and finite element methods for realistic problems. For genuinely time dependent problems, special care had to be taken in order to preserve accuracy. Small errors that do not show up in steady state calculations can be amplified and ruin the total accuracy. Time dependent boundary conditions may also pose problems. We addressed those issues in our research efforts. The recent advent of parallel computers poses a special challenge to the users of high-order methods. Issues in parallel computing for the simulations of incompressible and compressible flows has been treated.
