The results of a theoretical study of the special detonation regime that arises in a pulse detonation device with a variable cross section combustion chamber are presented. The problem is solved analytically within the framework of the one-dimensional approximation. In contrast to the standard version of arbitrary discontinuity disintegration, the problem is solved for a variable cross section at the location of the diaphragm. Since the pulse detonation device operated with a valveless system of fuel and oxidizer supply, a fuel flowed through it over the entire period before spark ignition. This peculiarity of the operation of the combustion chamber was also taken into account. The proposed approach was used to perform calculations for methane-oxygen mixtures, for which extensive experimental data exist. The calculation results are compared to the available experimental data. 相似文献
