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 compressor and find out background causes of the change in compressor performance. Swirl distortion

Experimental Investigation of Rotating Instability in an Axial Compressor with a Steady Swirl Distortion Inlet [PDF]
Energies, 2021 In this paper, an experimental study was carried out on the rotating instability in an axial compressor subjected to inlet steady paired swirl distortion. In order to deepen the understanding of the rotating stall mechanism under inlet steady paired swirl distortion, the dynamic-wall static pressure near the rotor tip was monitored to characterize the ...

Assessment of Total Pressure and Swirl Distortions in a Busemann Inlet at Mach 6
Journal of Applied Fluid Mechanics, 2023 Flow distortions in high-speed inlet systems are complex, and high-performance air-breathing propulsion systems. In this paper, large eddy simulations are performed to study the total pressure and swirl distortions in a Busemann inlet at freestream Mach number 6.

Unsteady Swirl Distortion in a Short Intake Under Crosswind Conditions
AIAA SCITECH 2024 ForumUnder crosswind operating conditions, the flow field of an aero-engine intake can be characterized by notable unsteady flow distortion. These distortions are typically associated with flow separation within the intake as well as with the ingestion of the ground vortex.

Aerodynamic Behavior of a Transonic Compressor Under VIGV-Induced Swirl Distortion
Proceedings of Global Power & Propulsion SocietyIn this paper, the effects of swirl distortion on a 1.5-stage transonic axial compressor are investigated. The experiments were carried out at the transonic compressor test rig (TCD2) at Technical University of Darmstadt. The rig is representative of a modern gas turbine front stage.

Effects of Swirl Distortion on Flow Field and Blade Load of a Centrifugal Compressor
Applied Mathematics and Nonlinear SciencesAbstract On the turbocharger, two forms of intake pipe, bending and torsion, are usually used, which leads to a vortex at the inlet of the blade. It has been found that double vortices and massive vortices play a significant role in the working characteristics of the compressor. This project intends to conduct a systematic theoretical
