Direct Simulation: Review and Comments

Abstract

The session entitled “Direct Simulation” comprised six invited papers, each illustrating timely and interesting applications of CFD methodology to aeroacoustics. Probably the most important aspect of the presentations, however, was the fact that each pointed up issues that are and will be of major concern as computational aeroacoustics (CAA) evolves into a working discipline. In this review, an attempt is made to provide a brief summary of the thrust of each of the contributions to the session as well as, where appropriate, some highlights of computational issues raised explicitly or implicitly by their authors. Further, the review contains some observations on these issues. To some extent, these represent personal views of the current author, but they are also meant to reflect the outcome of discussions that occurred during the panel session held at the conclusion of the ICASE/NASA Workshop.
