| titleOfInvention | An experimental device for the combined generation of sound waves and pressure oscillations in a high-pressure combustion chamber |
| abstract | The utility model relates to combustion experiment technology, and aims to provide an experiment device for jointly generating high-pressure combustion chamber sound waves and pressure oscillations. It includes a high-pressure combustion chamber enclosed by a pressure-resistant cavity wall and provided with a sample stage and an observation window. At least one side of the high-pressure combustion chamber is provided with a horn installation chamber that communicates with its internal cavity, and a horn installation chamber is installed in the horn installation chamber. Sonic horn, the center of its bell mouth faces the sample stage, and the burning position of the sample is located on the symmetry axis of the sonic horn; connected to the signal generator. The utility model can conveniently adjust the frequency of occurrence of sound waves and the intensity of sound pressure, and can simulate various unstable combustion conditions with different pressure oscillation frequencies more comprehensively and accurately. The method of acoustic excitation response can better solve the problem of coexistence of multiple fields, and more realistically simulate the complex and unstable combustion conditions in the combustion chamber of the actual rocket engine. |
