Abstract

The development of computational fluid dynamics (CFD) methods for unsteady aerodynamic analysis is described. Special emphasis is placed on considerations that are required for application of the methods to unsteady aerodynamic flow problems. Two broad categories of topics are discussed including grid considerations and algorithm development considerations, and example calculations are presented to illustrate the major points. Although the primary application of these CFD methods is to relatively low-frequency oscillatory phenomena such as flutter, the ideas that are presented may be of value to developers of computational aeroacoustics methods for predicting high-frequency acoustics.
