Flow field behind a complex total pressure distortion screen
Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2019The flow field behind a complex total pressure distortion screen is investigated experimentally and numerically. The distortion screen is designed using an established design methodology and fabricated by water-jet cutting technique.

A Centrifugal Compressor Operability Correlation With Combined Total Pressure and Swirl Distortion
Volume 1: Aircraft Engine; Fans and Blowers; Marine; Honors and Awards, 2017 Inlet swirl distortion has become a major area of concern in the gas turbine engine community. Gas turbine engines are increasingly installed with more complicated and tortuous inlet systems, like those found on embedded installations on Unmanned Aerial Vehicles (UAVs) and Auxiliary Power Units (APU).

Total pressure distortion levels at the aerodynamic interface plane of a military aircraft
The Aeronautical Journal, 2015AbstractMilitary aircrafts are often subjected to severe flight maneuvers with high Angles-of -Attack (AOA) and Angles of Sideslip (AOSS). These flight attitudes induce non-uniform in flow conditions to their gas turbine engines which may include distortion of inlet total pressure and total temperature at the Aerodynamic Interface Plane (AIP ...

Computational Simulation of Dynamic Total-Pressure Distortion in an S-Diffuser
48th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2012A prediction of dynamic pressure distortion has been made with time-accurate CFD technology. Comparisons were made between CFD and test data for steady-state and dynamic total-pressure obtained at the AIP of an S-duct. These comparisons included mean, standard deviation, spectrum and correlation properties.

Effects of Inlet Total Pressure Distortion on the Performance of a Two-Stage Transonic Fan
Volume 12A: Turbomachinery — Axial Flow Fan and Compressor AerodynamicsImproving the understanding of the interaction between multistage fan and an inlet total pressure distortion is benefical to design an advanced compression system and stabilizing measures with strong anti-distortion ability.

A stochastic pulsation total pressure model and reconstruction of actual distortion patterns
Physics of FluidsThis paper proposes a reconstructed method to simulate the total pressure distortion pattern produced by a baffle plate, utilizing a random sampling technique based on Pearson spatial correlation. The method employs the ratio of the pulsating pressure ΔP
