| description | The invention relates to devices for turbulating and accelerating a flame front, intended for use in technological and energy installations which operate by means of the detonation combustion of gaseous or atomized liquid fuel. Proposed is a device for turbulating and accelerating a flame front, which comprises a housing, provided with a set of obstacles/turbulators, and an ignition source. The set of obstacles/turbulators is in the form of perforated plates installed in cross-sectional planes of the housing, and the outlet of the housing ends with a nozzle. The apertures in neighboring perforated plates are offset from one another. The size of the apertures in all of the perforated plates remains constant or changes in accordance with the distance from the ignition source, and in the first plate the diameter of the apertures exceeds a maximum extinguishing size. The nozzle is subsonic or supersonic. The proposed device provides for quickly creating developed turbulence and a high flame front speed, as well as a rapid increase in pressure within the semi-closed volume of the device housing. As a result, a shock wave is formed having parameters which are sufficient for a rapid and reliable transition from combustion to detonation.
L'invention concerne des dispositifs de tourbillonnement et d'accélération du front de flamme destinés à s'utiliser dans des installations technologiques et énergétiques en mode de combustion par détonation de combustible gazeux ou liquide atomisé. On propose un dispositif de tourbillonnement et d'accélération du front de flamme comprenant un corps avec un ensemble de chicanes de tourbillonnement et une source d'allumage. L'ensemble de chicanes de tourbillonnement se présente comme un ensemble de plaquettes perforées montées dans des plans de sections transversales du corps, et le corps se termine à la sortie par une tuyère. Les orifices dans les plaquettes voisines perforées sont décalées les unes par rapport aux autres. La taille des orifices dans les plaquettes perforées reste constante ou varie à mesure que l'on s'éloigne de la source d'allumage; dans la première plaquette, la taille des orifices dépasse la taille maximale d'extinction des orifices. La tuyère peut être subsonique ou supersonique. Le dispositif permet d'assurer la création d'une turbulence développée et d'un front de flamme rapide ainsi que d'augmenter rapidement dans le volume partiellement clos de son corps.
