Abstract

Analyzed the using of mathematical modeling of noise silencers for the power industry. Results allow to determine its acoustic characteristics. The most important characteristics of silencers are their acoustic efficiency and aerodynamic drag. These two factors need to consider together. Aerodynamic drag imposes restrictions on the use of silencers. Improvement in the design of industrial silencers leads to the sophistication of their shapes. Difficulties arise to use known formulas for calculating the acoustic efficiency of such silencers. Analyzed the mathematical models and the physical characteristics of materials. Also, information on material properties depending on the selected model. Discussing the information about the limits of applicability dissipative silencers models. Carried out a mathematical simulation of a silencer. Results compared with known acoustic efficiency from the experiment for verification. Presented the results of modeling a silencer with variable plate thickness.
