An efficient Wave Based Method for axisymmetric acoustic-poroelastic problems
نویسنده
چکیده
The most commonly used prediction techniques to study the steady state behaviour of coupled acousticporoelastic problems are based on the Finite Element Method. However, due to the large computational load when frequency increases, these methods are restricted to low frequency problems. Recently, a Wave Based Method was developed to tackle this type of problems in a more efficient way. The method has proven to be very efficient for 2D coupled acoustic-poroelastic problems and can be applied in a wider frequency range as compared to standard techniques. This paper extends the framework of the Wave Based Method for coupled acoustic-poroelastic problems to axisymmetric geometries. An axisymmetric wave function set is derived both for acoustic and poroelastic problem domains and can be applied within the concept of the Wave Based Method. Two numerical validation examples show the efficiency of this approach.

An efficient wave based method for 2D dynamic poroelastic problems with corner stress singularities
Recently, a wave based method was developed to efficiently model the harmonic behavior of poroelastic materials. This novel method relaxes the frequency limitations of the finite element method by using exact solutions of the governing equations to approximate the field variables. However, in the case that the stress fields exhibit a singularity, the Wave Based Method suffers from convergence p...

S U M M A R Y We present a derivation of the equations describing wave propagation in porous media based upon an averaging technique which accommodates the transition from the microscopic to the macroscopic scale. We demonstrate that the governing macroscopic equations determined by Biot remain valid for media with gradients in porosity. In such media, the well-known expression for the change i...

متن کاملA High Order Approximation of the Two Dimensional Acoustic Wave Equation with Discontinuous Coefficients
This paper concerns with the modeling and construction of a fifth order method for two dimensional acoustic wave equation in heterogenous media. The method is based on a standard discretization of the problem on smooth regions and a nonstandard method for nonsmooth regions. The construction of the nonstandard method is based on the special treatment of the interface using suitable jump conditio...
متن کاملA Fictitious Domain Decomposition Method for High Frequency Acoustic Scattering Problems
It is well known that most PDE problems defined over an axisymmetric domain can be efficiently solved by a Fourier based solution method. However, for many applications, the underlying computational domain is not entirely axisymmetric, but has one or several major axisymmetric subdomains. For such problems, an axisymmetric analysis method is not applicable, and a straightforward one can be inef...
