This work extends the application of the finite volume method to predict the acoustic performance of the water muffler with the consideration of elastic walls. The three-dimensional time-domain finite volume method and the improved time-domain impulse method are employed to predict the acoustic attenuation characteristics of mufflers. The present results agree well with analytical solutions and numerical results obtained by finite element method with commercial codes. The effects of different thicknesses of elastic end cavity wall, elastic tube, and cavity walls on acoustic characteristics of a water-filled Helmholtz resonator are investigated. An attempt to simplify the present method with the effective sound speed has been implemented and discussed.

“…In the field of sound and vibration, Toyoda and Takahashi [7] have used the LE equations to model the impact sound in atwo-story building and solved it using the FDTD method. Another example is by Xuan et al who ap-plied the LE equations to the structural-acoustic problem and solved it using the finite volume method (FVM) [ 8]. Additionally,B ermúdez et al have modelled the vibroacoustic problem of a3 -D vessel filled with fluid using LE equations and used the finite element method (FEM) to calculate its eigenvalues [9].…”

This work presents a numerical solution of the forced plate vibration problem using the nodal discontinuous Galerkin (DG) method. The plate is modelled as a three-dimensional domain, and its vibration is governed by the linear elasticity equations. The nodal DG method discretises the spatial domain and computes the spatial derivatives of the equations element-wise, while the time integration is conducted using the Runge-Kutta method. This method is in particular of interest as it is very favourable to carry out the computation by a parallel implementation. Several aspects regarding the numerical implementation such as the plate boundary conditions, the point force excitation, and the upwind numerical flux are presented. The numerical results are validated for rectangular concrete plates with different sets of boundary conditions and thicknesses, by a comparison with the exact mobilities that are derived from the classical plate theory (CPT) and the first order shear deformation theory (FSDT). The plate thickness is varied to understand its effect regarding the comparison with the CPT. An excellent agreement between the numerical solution and the FSDT was found. The agreement with the CPT occurs only at the first couple of resonance frequencies, and as the plate is getting thinner. Furthermore, the numerical example is extended to an L-shaped concrete plate. The mobility is then compared with the mobilities obtained by the CPT, FSDT, and linear elasticity equations.
