Abstract

Abstract

An improved expansion chamber hydraulic noise suppressor with a compressible polyurethane liner was introduced to improve the pulsation attenuation performance of conventional suppressors. The filtering characteristics of this improved configuration were studied based on the characteristics of distributed and lumped parameters. First, a distributed parameter model of a conventional expansion chamber was developed using a one-dimensional (1D) analytical approach. Theoretical insertion loss (IL) is in good agreement with the experimental results. This illustrates that the method is also applicable to hydraulic suppressors. Then, a distributed parameter model of the perforated tubes in this improved structure was developed by utilizing the 1D method. A lumped parameter model works well for modelling the behaviour of the compliant lining part. Finally, the effects of voiding, porosity, and hole diameters on the performance of the improved expansion chamber hydraulic suppressor were studied. The results show that within frequencies of 500 Hz, voided urethane lining can remarkably improve IL at 2.76, 4.14 MPa, and 4.83 MPa. IL is affected by different hydrostatic pressures, regardless of whether the liner is voided or not. The effect of porosity and hole diameters on IL is marginal.
