The harmonic adjoint approach to unsteady turbomachinery design

Abstract:

In recent years, there has been rapid progress in aerodynamic optimization methods which use adjoint flow analysis to efficiently calculate the sensitivity of steady-state objective functions to changes in the underlying design variables. This paper shows that the same adjoint approach can be used in turbomachinery applications in which the primary concern is blade vibration due to harmonic flow unsteadiness.The paper introduces the key engineering concepts and discusses the derivation of the...
