An experimental investigation on the interaction between inlet swirl distortion and a low-speed axial compressor [PDF]
Science Progress, 2020 The aim of this article mainly lies in two aspects. The first is to investigate the effect of inlet swirl distortion on the performance and stability of a low-speed compressor experimentally. The second is to quantify swirl pattern revolution through the

Influences of micro ramp vortex generators on the performance of flush waterjet propulsor [PDF]
Scientific ReportsAn array of micro-ramp vortex generators (MRVGs) is deployed on the bottom of the ship’s hull just before the inlet, aiming to mitigate flow separation on the ramp wall at low inlet velocity ratios (IVR).
