Development and Applications of a Stage Stacking Procedure [PDF]
, 2012 The preliminary design of multistage axial compressors in gas turbine engines is typically accomplished with mean-line methods. These methods, which rely on empirical correlations, estimate compressor performance well near the design point, but may ...

Full annulus simulation on a multistage axial-centrifugal combined compressor
Journal of the Global Power and Propulsion SocietyAxial-centrifugal combined compressors are widely used in small and medium aero-engines. This study aims to investigate the performance and flow characteristics of a multistage axial-centrifugal compressor using annulus unsteady simulation. The compressor comprises three axial stages and one radial stage, including the inlet and outlet guide vanes. The
