Experimental analysis of the pressure–velocity correlations of external unsteady flow over rocket launchers [PDF]

, 2013
Based on simultaneous wall pressure and velocity measurements, the aerodynamic load of a launcher body model is investigated. Two different configurations are considered in order to study the influence of geometrical artifacts on the after body flow and ...

Numerical Analysis of One-dimensional Mathematical Model of Blood Flow to Reproduce Fundamental Pulse Wave Measurement for Scientific Verification of Pulse Diagnosis

Journal of Biomechanical Science and Engineering, 2011
Pulse diagnosis in traditional Chinese medicine is said to be able to detect not only illness but also decline of health in the patients from tactile sense of the pulse in the radial artery at the wrists.

Pulse wave propagation and velocity in aneurysmal aorta using FSI model [PDF]

Research & Knowledge, 2016
The pulse wave velocity (PWV) has been shown to be associated with the properties of blood vessels and a cardiovascular risk factor, such as an aneurysm. The global PWV estimation is applied in conventional clinical diagnosis.

Ab initio study of the elastic behavior of MgSiO3 ilmenite at high pressure [PDF]

, 1999
We investigate the athermal high pressure behavior of the elastic properties of MgSiO3 ilmenite up to 30 GPa using the ab initio pseudopotential method. Our results at zero pressure are in good agreement with single-crystal elasticity measurements.

Numerical Study of Coupled Fluid and Solid Wave Propagation Related to the Cladding Failure of a Nuclear Fuel Rod

Applied Sciences, 2022
Fuel rod cladding failure in a nuclear reactor produces different phenomena related to vibrations and fluid–structure interaction. The most significant aspect of those phenomena is the creation of a pressure wave at the failure position and its ...

Wave Propagation in Granular Materials [PDF]

, 2005
Wave propagation is a fundamental property of all physical systems. The wave speed is directly related to the compressibility of the system and determines the rate at which local disturbances are propagated into the bulk of the material.

Insights into the underlying reaction kinetics of gasoline–ethanol interactions and their effects on the auto-ignition characteristics of gasoline/ethanol blends

Applications in Energy and Combustion Science
Ethanol-blended gasolines show enhanced anti-knock behavior in spark-ignition engines. Fundamental experimental investigations on their auto-ignition behavior are however scarce in the literature.

General Analytical Method to Predict the Spatial–Temporal Distribution of Extreme Pressure in High-Speed Railway Tunnels in the Post-Train Stage

Applied Sciences, 2023
Long-duration aerodynamic pressure fluctuation in high-speed railway tunnels in the post-train stage causes fatigue damage to tunnel structures and facilities. It increases the risk of accidents and requires in-depth research.

WAVE MEASUREMENTS BY A PRESSURE TYPE WAVE GAUGE

Coastal Engineering Proceedings, 1968
The paper deals with comparative measurements of irregular model waves by a pressure type wave gauge and a continuous wire wave gauge. For the depth and wave conditions used in the study it is concluded that the height of individual waves obtained by a pressure type gauge and using the first order wave theory may be in considerable error, while wave ...

A new approach to investigate wave dissipation in viscoelastic tubes: Application of wave intensity analysis

, 2005
Wave dissipation in elastic and viscoelastic medium has been investigated extensively in the frequency domain. The aim of this study is to examine the pattern of wave dissipation in the time-domain using wave intensity analysis.
