Abstract
Abstract : This is a CAA (computational aeroacoustics) primer written specifically for AEDC. This is not a document written for research in CAA. It is to be a user's guide for practicing engineers who have responsibilities of solving (through prediction) or resolving (through better understanding) aeroacoustics problems by extensive computation. Oftentimes established codes that may or may not have been designed for aeroacoustics applications are used. For this reason the accuracy and validity of the computed solution may be in question. In this situation this document serves to provide a reference to a proper CAA approach. CAA problems are very different from CFD (computational fluid dynamics) problems. In some situations special CAA treatments are required that are not encountered in CFD. Such methods are therefore not available in standard CFD or numerical analysis references. This document is to offer a discussion of a variety of CAA methods most of which are developed only relatively recently.
