Method and pulse detonation - combustion chamber to the periodic detonating combustion of a combustible mixture

摘要

Combustible mixture is periodically detonated and combusted in a chamber, to which fuel and oxidant are fed separately. A separation zone of incombustible material separates the hot combustion prods. of the previous cycle from a newly fed charge of mixture, and is cooled to a temperature below that of the combustion prods. of the previous cycle. Preferably the separation zone is produced by cooling the combustion prods., which are compressed impulsively into the feed ducts by a short-time rise of pressure in the combustion chamber by detonating combustion of the mixture, below the ignition temperature of the mixture. Appts. may be used for MHD electricity generation, or production of periodic light, strong density fluctuations, or combustion in internal combustion engines.
