Optimization design of dual microjets for the shock wave/boundary layer interaction control in the supersonic flow

open access: yesAIP Advances, 2023
The shock wave/boundary layer interaction phenomenon is harmful to the performance improvement of the hypersonic vehicle, and the microjet flow control scheme was introduced to minimize the total volume of the separation bubble and maximize the total ...

Gravity wave amplification and phase crest re-organization over a shoal [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2011
In this experimental work, both wave amplification and phase evolution, due to a submerged mound, are studied. In addition to the classical surface wave measurements, the experimental study takes advantage of photographs that underline crest re ...

Flow Separation Control in a Curved Diffuser with Rigid Traveling Wave Wall and Its Mechanism

open access: yesEnergies, 2019
Traveling wave wall is a useful method to suppress flow separation. However, the interaction between the traveling wave wall and unsteady separation flow is complex, which causes difficulty in discovering the corresponding mechanism.

P8.2 ARTERIAL WAVE REFLECTIONS: LOOKING BEYOND THE FIRST HARMONIC AND PRESSURE INFLECTION POINTS TO ASSESS LATE-SYSTOLIC VENTRICULAR LOADING

open access: yesArtery Research, 2015
Background: Late-systolic ventricular loading is associated with impaired relaxation and adverse remodeling. Standard indices of relative wave reflections such as augmentation index (AIx) and reflection magnitude (RM) from wave separation analysis blend ...

Mode Separation for Multimodal Ultrasonic Lamb Waves Using Dispersion Compensation and Independent Component Analysis of Forth-Order Cumulant

open access: yesApplied Sciences, 2019
Ultrasonic Lamb wave testing has been successfully applied in nondestructive testing. However, because of Lamb wave multimodal and dispersion characteristics, the received signals are often multimodal and overlapping, which makes them very complicated ...

Determination of wave vectors using the phase differencing method [PDF]

open access: yesAnnales Geophysicae, 2013
Due to the collisionless nature of space plasmas, plasma waves play an important role in the redistribution of energy between the various particle populations in many regions of geospace. In order to fully comprehend such mechanisms it is necessary to

Wave Separation Analysis to Assess Cardiovascular Alterations Induced by Sepsis

open access: yesIEEE Transactions on Biomedical Engineering
Sepsis induces a severe decompensation of arterial and cardiac functional properties, leading to important modifications of arterial blood pressure (ABP) waveform, not resolved by recommended therapy, as shown by previous works. The aim of this study is to quantify the changes in ABP waveform morphology and wave reflections during a long-term swine ...
