Characteristics of unsteady total pressure distortion for a complex aero-engine intake duct
Aerospace Science and Technology, 2018 Some types of aero-engine intake systems are susceptible to the generation of secondary flows with high levels of total pressure fluctuations. The resulting peak distortion events may exceed the tolerance level of a given engine, leading to handling ...

Distortion of the Intracranial Pressure Waveform by Extraventricular Drainage System [PDF]
IEEE Transactions on Biomedical Engineering, 2021 To investigate whether intracranial pressure (ICP) waveform measurements obtained from extraventricular drainage (EVD) systems are suitable for the calculation of intracranial elastance (ICE) or cerebrovascular pressure autoregulation (PAR) indices.The transfer characteristic of an EVD system is investigated by its step and frequency responses with ...

Numerical simulation of S-shaped inlet under the intake total pressure distortion [PDF]
MATEC Web of Conferences, 2022 During the development of the stealth fighter, the S-shaped inlet enters the designer’s vision because it has better stealth than bump inlet and straight inlet. During the use of the S-shaped inlet, due to its structural reasons, secondary flow is likely

Using Tip Injection to Stability Enhancement of a Transonic Centrifugal Impeller with Inlet Distortion [PDF]
Journal of Applied Fluid Mechanics, 2022 This paper aims to understand the effects of circumferential inlet distortion and tip injection on a transonic impeller performance and flow field. For distorted inflow, the impeller is subjected to a stationary 120-degrees circumferential total pressure

Volume 2A: Turbomachinery — Axial Flow Fan and Compressor Aerodynamics, 2021 Future jet engines with shorter and thinner intakes present a greater risk of intake separation. This leads to a complex tip-low total pressure distortion pattern of varying circumferential extent.

Two-tone distortion in intracochlear pressure [PDF]
The Journal of the Acoustical Society of America, 2005 Two-tone distortion was measured in the intracochlear pressure in the base of the gerbil cochlea, close to the sensory tissue, where the local motions and forces of the organ of Corti can be detected. The measurements probe both the underlying nonlinear process that generates two-tone distortion, and the filtering and spreading of the distortion ...
