Improvement of the Parallel Compressor Model and Application to Inlet Flow Distortion

open access: yesInternational Journal of Turbomachinery, Propulsion and Power, 2021
This paper introduces a semi-analytical approach which enables one to deal with distorted inflow in axial fans or compressors. It is inspired by the classical parallel compressor (PC) theory but relies on a local flow-loading coefficient formalism. It is
