An unstructured finite-volume Helmholtz method with perfectly matched layers for heterogeneous two-phase acoustics
This paper presents a cell-centred unstructured finite-volume method for time-harmonic two-phase acoustics. A volume-fraction representation supplies density and acoustic compressibility. Face fractions average available neighbouring planar interface cuts independently of velocity direction, retaining the established o...
