2022, Applied Mathematical ModellingCitation Excerpt :Currently, the Perfectly Matched Layer (PML) is a standard technique to model wave propagation phenomena in unbounded domains, in such a way that the computational domain of interest is surrounded by an absorbing artificial layer, which does not introduce any spurious reflections in the solution of the original problem. It was first proposed by Berenger [9] for electromagnetic problems but it is also widely used in other fields as acoustics (see Abarbanel et al. [10], Qi and Geers [11], Bermúdez et al. [12]), or linearised water waves (see Cohen and Imperiale [13]). In the present approach the two-dimensional Cartesian PML model has been extended to three dimensions in cylindrical coordinates with the aim of absorbing the outgoing wave pattern generating by the floating body (i.e., the Kelvin wake) and preserving the structure of the convected terms presented in the free boundary condition.
