Application of shock tubes to transonic airfoil testing at high Reynolds numbers [PDF]

Performance analysis of a gas-driven shock tube shows that transonic airfoil flows with chord Reynolds numbers of the order of 100 million can be produced, with limitations being imposed by the structural integrity of the facility or the model.

Stabilisation of the lattice-Boltzmann method using the Ehrenfests' coarse-graining

, 2006
The lattice-Boltzmann method (LBM) and its variants have emerged as promising, computationally efficient and increasingly popular numerical methods for modelling complex fluid flow.

Wyznaczanie Energii Dostarczonej do Elektrycznej Rurki Uderzeniowej

Engineering Transactions, 1966
The present paper describes a method for determining the energy input in an electric shock tube based on the relations, obtained experimentally, between the intensity of current and the time in the discharge circuit including a shock tube or if the ...

Plasma spectroscopy of uranium and tungsten, part 1 [PDF]

Results of research on uranium and tungsten spectra are summarized. Measurements of visible line spectra and opacities were carried out on shock tube plasmas which, prior to shock compression, were mixtures of rare gases and UF6 or WF6.

Obliczanie Parametrów Przepływu w Rurze Uderzeniowej z Uwzględnieniem Jonizacji

Engineering Transactions, 1966
The aim of the present paper is to determine the thermodynamic parameters of an electric shock tube. The flow is described by means of the classical shock tube. The body is described using the scheme of a multiply ionized gas introduced by A. SZANIAWSKI,

Modeling of detonation transition through the field of mixing the reacting and inert gases

MATEC Web of Conferences, 2017
The non-stationary problem of exciting a plane shock wave by gas detonation in a tube is numerically solved. The case, when the field of mixing the reacting and inert gases filling the closed tube end has finite size, is considered.

Microscopic phenomena and a modern approach to turbulence [PDF]

The use of an arc driven shock tube as a technique in the study of turbulence and evidence to support a kinetic theory of turbulence are described. Topics covered include: (1) reaction rate distortion in turbulent flow; (2) turbulent bursts in a shock ...

Blast tube design: How shape and size influence the resultant shock wave

AIP Advances
Shock tubes and tunnels are often used in research settings as a way of producing high pressure shock waves in a smaller footprint or without the use of explosives. However, there is no standard geometric design across laboratories.
