Efficient Wave Based Models for Acoustic Scattering and Transmission Problems Using Point Source and Plane Wave Excitation
نویسندگان
چکیده
The wave based method (WBM) is an efficient deterministic prediction method for the analysis of steady-state acoustic problems. It offers an alternative to the finite element and boundary element method, especially in the mid-frequency range, where these element based methods are impaired by their computational burden. This paper discusses the use of new source formulations in WB models for two-dimensional unbounded acoustic problems. These source formulations allow the WBM to tackle general acoustic radiation and transmission problems. Numerical validation examples illustrate the advantageous properties of the considered approach.
