RESEARCH ON DESIGN TECHNOLOGY OF SIMULATING PLATES FOR COMPRESSOR TOTAL PRESSURE DISTORTION

Aerodynamic stability testing of compressors requires the use of distortion generators to simulate the inlet total pressure distortion flow field. Traditional design of such generators involves a repetitive process of trial-and-error, testing, and modification, which leads to long design cycles and difficulties in ensuring accuracy.

Effect of screen-induced total-pressure distortion on axial-flow compressor stability [PDF]

, 1974
An experimental investigation was made to determine the effects of screen-induced total-pressure distortions on two J85-GE-13 turbojet engines. Results were compared to those from a previous program run with a third engine.

Aerodynamic optimization for stability improvement of a centrifugal compressor using arbitrary-shape volute design

Case Studies in Thermal Engineering
In this paper, a novel arbitrary shape design strategy for centrifugal compressor volutes is proposed and implemented for flow control of circumferentially-induced pressure distortion at design and off-design conditions.

On the Distortion of a Copula and its Margins [PDF]

This article examines the notion of distortion of copulas, a natural extension of distortion within the univariate framework. We study three approaches to this extension: (1) distortion of the margins alone while keeping the original copula structure, (2)
