Experimental investigation of the developed focusing elements for generating extreme pressures in a diaphragmless shock tube. [PDF]
Sci RepHigh-pressure shock waves of several tens of MPa are of importance in many applications, such as material fabrication and testing, combustion chemistry and metrology. Controlled and predetermined shock waves can be generated by a shock tube, where the sudden expansion of a high-pressure driver gas into a low-pressure driven gas caused by the ...

A review of diaphragmless shock tubes for interdisciplinary applications [PDF]
Progress in Energy and Combustion Science, 2022 Shock tubes have emerged as an effective tool for applications in various fields of research and technology. The conventional mode of shock tube operation employs a frangible diaphragm to generate shockwaves. The last half-century has witnessed significant efforts to replace this diaphragm-bursting method with fast-acting valves.

Note: An improved driver section for a diaphragmless shock tube
Review of Scientific Instruments, 2015 Improvements to equipment lifetime and measurement reproducibility have been made by modifying the actuating mechanism of a diaphragmless shock tube that is used for high temperature gas kinetic studies. The modifications have two major benefits while retaining the simplicity of the original apparatus.

Diaphragmless single-pulse shock tube for high-temperature chemical kinetics studies
Review of Scientific Instruments, 2019 Single-pulse shock tubes are effective tools for measuring chemical kinetics at high temperatures, typically (900–1400) K. However, the use of a diaphragm for shock generation leads to significant shock-to-shock inconsistencies in temperature for a constant initial pressure ratio across the discontinuity.

A Newly Developed Large Diameter Diaphragmless Shock Tube for Studies on CO2-N2 Gas-Dynamic Laser
Plasma and Fusion Research, 2007 A large diameter diaphragmless shock tube has been recently developed and designed to perform detailed studies of CO2-N2 gas-dynamic laser (GDL). This large diameter diaphragmless shock tube offers various advantages over the conventional shock tubes (diaphragm-type) as longer test times, higher degree of reproducibility of shock-tube data, and ...

Fundamental Study on Operational Parameters of Diaphragmless Shock Tube [PDF]
MATEC Web of Conferences, 2018 This paper shows influences of initial conditions on a diaphragmless shock tube operation. This facility consists of a driver tube, a driven tube and a damp tank. The driver tube has a circular cross section with diameter of 150 mm and the driven tube, a rectangular cross section (60 mm x 150 mm).

Diaphragmless shock tube for primary dynamic calibration of pressure meters
ACTA IMEKO, 2020 In conventional shock tubes with a diaphragm many effects related to the burst of the diaphragm can influence the shock formation and thus prevent an ideal pressure step change predicted by the shock tube measurement model being generated. This paper presents a newly developed diaphragmless shock tube, in which a diaphragm is replaced with a quick ...
