... axial compressor facility. For the high-speed centrifugal compressor, stall was encountered unexpectedly during speed transients. The three-stage axial compressor features both modal- and spike-type stall inception depending on the rotor tip clearance levels. Therefore, these data sets provide a unique...

Measurement techniques Compressor stall Surge Centrifugal pumps Operability First, we compare the simplified coupling model (Fig. 4 ) with the numerical calculation of torsional stiffness using the same geometry (referenced by ANSI/AGMA 9004 standard). The full 3D FEM based on the axisymmetric...
