A numerical study of flutter in a transonic fan

Abstract:

The bending mode flutter of a modern rr transonic fan has been studied using a quasi-three-dimensional viscous unsteady CFD code. The type of flutter in this research is that of a highly loaded blade with a tip relative Mach number just above unity, commonly refer red to as transonic stall flutter. This type of flutter is often encountered bz modern wide chord fans without a part span shr-oud. The CFD simulation uses an upwinding scheme with Roe's third-order flux differencing, and Johnson an...
