Reduction in Noise Pollution of a Gas Power Plant under Construction Using Synthesis of Copper and Nickel Alloy Foam in a Simulated Setting

Noise pollution is one of the challenges of installing equipment and developing industries. The control of noise generated by small power plants is a necessity for its use development. Designing the synthesis of copper and nickel alloy foam and using this foam to reduce noise pollution in the exhaust is one of the effective methods to control and reduce noise pollution from power plants. The purpose of this study was to synthesize copper and nickel alloy foam and compare the effect of results of spl changes in software ANSYS for three ductless, ideal wall and multilayer wall modes at different frequencies. In this regard, the adjunct duct is modeled as 3D by software ANSYS, and the output sound intensity of the duct in the acoustic setting is analyzed in several different modes. The results show that three different modes in the exhaust output indicate that the multilayer wall at most frequencies reduces the sound pressure level relative to the ductless or ideal wall modes.
