Effects of flow instabilities on the linear analysis of turbomachinery aeroelasticity

Abstract:

The linear analysis of turbomachinery aeroelasticity is based on the linearization of the unsteady How equations around the mean flow field, which can be determined by a nonlinear steady solver. The unsteady periodic flow can be decomposed into a sum of harmonies, each of which can be computed independently by solving a set of linearized equations. The analysis considers just one particular frequency of unsteadiness at a time, and the objective is to compute a complex How solution that repres...
