Motion analysis of a diaphragmless driver section for a narrow channel shock tube

Shock Waves, 2008
We 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.

Analysis of a Quick-Acting Diaphragmless Shock Tube Driver

2015
Shock 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].

Improvement of a Diaphragmless Driver Section for a Small Diameter Shock Tube

2015
Recently, the micro-shock waves have attracted attention of researchers in several fields of science. It is well known that the shear stress and the heat transfer between a test gas and a wall lead to significant deviations from the normal theory of a shock wave propagating in a small diameter shock tube[1][2].

Characterization of a newly developed diaphragmless shock tube for the primary dynamic calibration of pressure meters

Metrologia, 2020
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.

Experimental study of toroidal shock wave focusing in a compact vertical annular diaphragmless shock tube

Shock Waves, 2009
The paper reports results of experiments regarding toroidal shock wave focusing in a vertical shock tube as a part of a series of converging shock wave studies. This compact vertical shock tube was designed to achieve a high degree of reproducibility with minimum shock formation distance by adopting a diaphragmless operating system.

A diaphragmless shock tube for high temperature kinetic studies

Review of Scientific Instruments, 2008
A 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.

A New-Conception, Electromagnetically Controlled, Diaphragmless Shock Tube

Volume 1: Turbo Expo 2003, 2003
A new conception, electro-magnetically controlled, diaphragmless shock tube was realized and tested in the laboratories of University of Florence. A piston separates the co-axial driver and driven sections. The piston is kept in position by a force of an electromagnet acting on an iron disc linked to its rod. In order to obtain very short opening time,

A New Fast Acting Valve for Diaphragmless Shock Tubes

2012
Conventional shock tubes usually use diaphragms to separate the driver and driven section from each other before experiment. Diaphragms have the advantage that they are easy to use and open nearly instantaneously. Nevertheless, this technique has also some disadvantages.
