... Abstract This paper continues previous research by the current authors in a series of papers describing the impact of multi-row interaction on the forced response behavior of embedded compressor rotors. Specifically, this work dives into an aspect of the embedded rotor forcing that has been...

...-order mode crossing. This crossing occurs at a slower speed, and higher-order crossings are difficult to predict due to their low response for this configuration. The paper focuses on the multi-row interaction at multiple operating points and the mistuned blade response prediction. The computational...

... at a downstream row. 2) The modal force prediction its impact on the multi-row unsteady aeromechanical influence. improved by ~10% for the 3-row case and 1% for the 4-row case The authors of this paper have talked about the multi-row and the values moved closer to the experimental values in both influence...

...Abstract Abstract This paper focusses on predicting the mistuned forced response behavior of an embedded compressor rotor blade row in a 3.5 stage axial compressor. The authors in previous papers studied the multi-row influence on the forcing function for multiple operating conditions...

...Abstract Abstract This paper focuses on the impact of multi-row interaction on the forced response behavior of an embedded compressor rotor at higher order modes. The authors in previous papers have discussed about the multi-row influence at the torsional mode resonant crossing and this paper...
