Prediction of the noise radiation of hermetic compressors utilizing the compressor simulation program and Finite Element Method (FEM)-Boundary Element Method (BEM) analyses.

Author(s) : ZHOU W., KIM J.

Summary

The complexity arising from the interactions between the pulsating flow, gas cavity and shell structure has been the major obstacle in realizing the prediction of the radiated sound level of hermetic compressors by a numerical simulation. The simulation program is used to calculate the unsteady flow inputs to the inside shell cavity of the compressor. A FEM-BEM approach is used to calculate the resulting shell motion and the radiated sound field.
