A diaphragmless shock tube for high temperature kinetic studies
Review of Scientific Instruments, 2008A novel, diaphragmless shock tube (DFST) has been developed for use in high temperature chemical kinetic studies. The design of the apparatus is presented along with performance data that demonstrate the range and reproducibility of reaction conditions that can be generated.

Characteristics of an annular vertical diaphragmless shock tube
Shock Waves, 2000Abstract. This paper reports on the characteristics of a compact vertical diaphragmless shock tube, which was constructed and tested in the Shock Wave Research Center to study experimentally the behavior of toroidal shock waves. It is 1.15 m in height and has a self-sustained co-axial vertical structure consisting of a 100 mm i.d.

A rapid opening sleeve valve for a diaphragmless shock tube
Shock Waves, 2011This paper describes a novel pneumatically operated diaphragmless shock tube valve that is capable of generating well-formed shock waves within a driven tube which has a length to diameter ratio of 122. Its development was motivated by the requirement for an automated shock tube—an application for which the conventional bursting diaphragm method is not

Analysis of a Quick-Acting Diaphragmless Shock Tube Driver
2015Shock waves play integral roles in many industrial, medical and scientific environments, consequently it is important to observe the behavior of these waves and how they interact with their surroundings; see the review paper by Takayama and Saito [1].

High-Frequency Generation of High-Pressure Pulses Using a Diaphragmless Shock Tube
1995We have developed a high-pressure pulse generator at a high repetitive rate by combining a diaphragmless shock tube with shock strengthening by area convergence. The diaphragmless shock tube generates shock waves with Mach numbers of up to 2 traveling in the tube at atmospheric pressure.

Abstract In conventional shock tubes with a diaphragm, many effects related to the burst of the diaphragm can influence shock formation, thus preventing an ideal pressure step change, as predicted by the shock tube measurement model being generated.

A pneumatic valve has been designed to replace diaphragms in shock tubes and a diaphragmless shock tube has been constructed for use with the pneumatic valve. Performance tests have been carried out for the shock tube. The present apparatus is shown to be capable of producing shock waves up to 3.5 in Mach number and be convenient to use.

Motion analysis of a diaphragmless driver section for a narrow channel shock tube
Shock Waves, 2008We set up a diaphragmless driver section as the first step towards developing a shock tube at microscale which has high experimental efficiency, independent of tube dimensions or the ratio of driver and driven pressure. The experiment described in this paper is performed by using our diaphragmless driver section.
