Vibrational effects on the dynamic pressure measurement standard based on a diaphragmless shock tube

open access: yesMeasurement: Sensors, 2021
This paper determines the vibrational effects on a diaphragmless shock tube, which was developed for dynamic calibrations of pressure transducers. First, the sensitivity to acceleration of the piezoelectric pressure transducer was determined by exciting ...

Research on the Application Performance of the Helmholtz High-Efficiency Wave-Elimination Chamber in Gas Wave Tubes

open access: yesEnergies, 2022
A gas wave refrigerator is a device that uses gas pressure to expand and refrigerate; the moving shock wave in the gas wave tube is the key to cooling.

Influence of multiple structural parameters on buffer performance of a thin‐walled circular tube based on the coupling modeling technique

open access: yesInternational Journal of Mechanical System Dynamics, 2022
Pyrotechnic devices are widely used in the aerospace and defense industries. However, these devices generate high‐frequency and high‐amplitude shock responses during their use, compromising safe operation of the system.

Miniature shock tube for laser driven shocks [PDF]

open access: yesReview of Scientific Instruments, 2010
We describe in this paper the design of a miniature shock tube (smaller than 1 cm3) that can be placed in a vacuum vessel and allows transverse optical probing and longitudinal backside extreme ultraviolet emission spectroscopy in the 100–500Å range. Typical application is the study of laser launched radiative shocks, in the framework of what is called

A study on characteristics of shock train inside a shock tube

open access: yesTheoretical and Applied Mechanics Letters, 2017
Shock tubes are devices which are used in the investigation of high speed and high temperature flow of compressible gas. Inside a shock tube, the interaction between the reflected shock wave and boundary layer leads to a complex flow phenomenon ...

Development of a high-performance cryogenic shock tube [PDF]

open access: yes, 1974
A cryogenic shock tube has been developed as a tool for research in fluid mechanics and low-temperature physics. The shock tube was designed to operate with the test section immersed in a cryogenic liquid.

Grid-converged Solution and Analysis of the Unsteady Viscous Flow in a Two-dimensional Shock Tube [PDF]

open access: yes, 2017
The flow in a shock tube is extremely complex with dynamic multi-scale structures of sharp fronts, flow separation, and vortices due to the interaction of the shock wave, the contact surface, and the boundary layer over the side wall of the tube ...
