A parametric study which investigates the influence of viscous effects on the damping
behavior of vibrating compressor cascades is presented here. To demonstrate the …

Numerical stall flutter prediction methods are much needed, as modern jet engines require
blade designs close to the stability boundaries of the performance map. A Quasi-3D Navier …

During the design of the compressor and turbine stages of today's aeroengines,
aerodynamically induced vibrations become increasingly important since higher blade load …

The objective of this paper is the numerical analysis and prediction of unsteady quasi 3D
flow through turbomachinery cascades with vibrating blades. The developed numerical …

The design of modern gas turbines is more and more based on flow simulations by
numerical calculation models. Due to the different influence parameters the development …

An efficient and accurate solver is developed to simulate the non-linear fluid-structural
interactions in turbomachinery flutter flows. A new low diffusion E-CUSP scheme, Zha CUSP …

A Navier–Stokes solution method with overset grids is applied to unsteady multipassage
cascade flows, and the unsteady blade loadings are compared against the single-passage …

Due to the trend in the design of modern aeroengines to reduce weight and to realize high
pressure ratios, fan and first-stage compressor blades are highly susceptible to flutter. At …
