Detonation in oxyhydrogen bubbled liquids
Symposium (International) on Combustion, 1982Shock wave propagation in glycerin with 70% Ar+30% (2H 2 +O 2 ) bubbles and associated bubble behaviors were observed in a vertical shock tube where the pressure ratio between the high and low pressure sections was p 4 /p 1 =15. It was found that once a bubble explosion started in the glycerin, it continued propagating, the amplitude and the ...

Oxyhydrogen burner for low-temperature flame fusion
Review of Scientific Instruments, 1993An oxyhydrogen burner as described in this article enables the growth of crystals by Verneuil’s technique at temperatures of about 1000 °C. The powder fed to the crystal passes along a low-temperature pathway through the flame, so that evaporation of volatile components is prevented.

Slowdown of oxyhydrogen detonation by surface catalysis
Symposium (International) on Combustion, 1977The propagation velocities of stoichiometric oxyhydrogen detonations were measured in thin tubes of different wall materials. From 4 to 6% velocity differences were observed consistently for pyrex and γ-alumina walls. By changing the tube geometries, it was confirmed that this velocity difference can be explained only by the catalysis of the wall ...

Heterogeneous chain propagation in a rarefied oxyhydrogen flame
Doklady Physical Chemistry, 2004In the 1950s and 1960s, Semenov’s theory of branched chain processes had become capable of quantitatively describing hydrogen combustion [1, 2], but the theory fit the experimental data only in the depth of the ignition peninsula. As reported in [3], Semenov and colleagues observed [1] a hydrogen combustion rate exceeding the theoretical expectations ...

The influence of the electrolyte parameters on the efficiency of the oxyhydrogen (HHO) generator
2014 18th International Symposium on Electrical Apparatus and Technologies (SIELA), 2014The electrolysis of water is an electrochemical process wherein hydrogen and oxygen are derived. The resulting mixture of oxygen and hydrogen is called oxyhydrogen or Brown's gas. This paper present an experimental study of the regime of operation of an oxyhydrogen (HHO) generator depending on the parameters of the electrolyte - concentration and ...
