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 …

Previous studies have demonstrated that shock wave focusing is an efficient method for
detonation initiation by creating hot spots in the interaction of shock-shock or the collision of …

Hydrogen is a key pillar in the global Net Zero strategy. Rapid scaling up of hydrogen
production, transport, distribution and utilization is expected. This entails that hydrogen …

A novel direct absorption spectroscopy gas sensing system based on end-to-end deep
neural networks was proposed for measurements of gas concentration. One-dimensional …

High-temperature methane and propane laminar flame speed measurements were
conducted behind reflected shock waves in a shock tube. A high-power Nd: YAG laser was …

Experimental and computational investigations are carried out to identify the generalized
criterion to predict the preignition tendency of methanol and ethanol mixtures in shock tubes …

The oxidation of ethanol was investigated in shock tubes by measuring ignition delay times
and water time history profiles. A laser absorption technique was used in the latter case …

Ignition delay times (IDT) of n-heptane, iso-octane, n-dodecane, and iso-octane/n-dodecane
blends, in stoichiometric mixtures with air, were measured behind reflected shock waves in a …

The work studies scenarios of self-ignition of hydrogen-air mixtures after a shock wave
reflects from a destructible barrier made of sand or a solid wall. The experiments were …

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 …
