Time-Accurate CFD Predictions and Data Validation for Side Load Generation by Flow-Structure Coupling in Over-Expanded Rocket Nozzles

The present paper validates results from numerical simulations for side load generation in rocket nozzles against related data from analytical models that are presently used for rocket engine nozzle design activities.Time-accurate two- and three-dimensional turbulent Navier–Stokes (N–S) computations are performed for separated flow in deflected and ovalized nozzles as well as for nozzles under forced harmonic oscillations. Based on this comparison conclusions are drawn concerning the validity of the physical model assumptions that the analytical design methods are based on.
