NON-STATIONARY VIBRATORY PROCESSES IN SEMI-OPEN PIPES

By Elena Nikolaevna Burnusenko

Abstract

The computer circuit for analysis of the non-steady forced non-lineat vibrations of the gas in the semi-open resonators by a pseudospectral method operating with the accurate gasodynamic equations without additional suppositions taking non-linear boundary conditions into consideration has been developed. The numerical and analytical analysis of the semi-open resonator as a thermoacoustic system has been performed. The analytical solution of the approximated model has been given. The conclusions about possibility and conditions of using the semi-open resonator as an acoustic cooling system (acoustic refrigerator) have been made. It is recommended to use the obtained results in the theoretical and applied investigations of the non-linear vibrating processes in the semi-open resonators in a number of the scientific organizations and higher educational institutionsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
