| Abstract: | The possibility of intensifying the mixing and combustion of hydrogen in the model channel during straight supply by means of acoustic–vortex oscillations generated in the injector is considered. The results of numerical computational studies in a two-dimensional formulation are presented. An increase hydrogen combustion efficiency in the model channel has been obtained in the presence of vortex oscillations in the injector compared with the case of its stationary outflow. The frequencies of own acoustic vibrations in the injector are analytically estimated. It is established that the vortex sound in the injector is realized at a frequency close to or equal to one of its own acoustic frequencies. The most intense pulsations of the hydrogen jet at the outlet of the injector occur at frequencies corresponding to transverse vibrations in the injector channel. [ABSTRACT FROM AUTHOR] |
