Empirical and analytical methods have been used for the design of spacecraft engine components as the thermally and mechanically high-loaded expansion nozzles of present launch systems. Recent progress in high-performance computing facilities permits the numerical simulation of the unsteady flow fields and the interaction with structural dynamics. The objective of the present study is to investigate the degree to which such numerical solutions can reproduce observed phenomena that cannot be described by empirical or analytical models.

Keywords:  Flow-structure interaction; Parallel algorithms; High-performance computing
