| Summary: | Gas sealing structures have been widely used in various engineering fields, and the gas leakage rate is one of the most important indicators for evaluating the sealing performance of sealing structures. In this paper, an aeroacoustic measurement method is proposed to measure the gas leakage rate by using one sound pressure sensor based on known location of a single leakage hole combining the aeroacoustic theory with numerical simulation results. First, the basic measurement principle is established using the Lighthill acoustic analogy method. Then, the finite element method is used to calculate the fitting parameters in leakage rate equations. Finally, the single-hole leakage experiments are carried out to verify the effectiveness of this gas leakage rate measurement method. The measurement results are in good agreement with the results recorded by flowmeters. |
