Benchmarking and Qualification of PAC-Femlab for Resonant Acoustic Chamber Design

摘要

The design of high-powered resonant acoustic systems capable of inducing large pressure oscillations in the 105 Hz to 106 Hz range requires a validated simulation platform, one that includes complexities of multi-dimensional fluid-structure interactions. Past efforts at designing such systems have relied mainly on time-consuming, trial-error based heuristic approaches (West et al, 1967; Taleyarkhan et al., 2002;2004). A robust design-cum-simulation platform is required to enable rapid strides and motivated this study for which the PAC-Femlab model was developed and successfully qualified against detailed experiment data as well as against data from a second independent experiment conducted elsewhere (Cancelos et al., 2004).
