A low Mach correction able to deal with low Mach acoustics

Abstract: HAL is a multidisciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d'enseignement et de recherche français ou étrangers, des labora… Show more

“…The all-Mach VFRoe scheme is stable. In fact, as for the constant porosity case, numerical tests seem to show that the all-Mach scheme is stable under a degenerated CFL condition which is exactly the half of the classical one (see [13,5] for more details). This justifies why all numerical results are obtained with CF L = 0.4.…”

“…Indeed, they do not allow to recover the incompressible limit as the Mach number tends to zero. Over the two last decades, a large amount of work has been dedicated to deriving fixes for the uniform porosity case: [23,28,29,13,37,12,15,33,7,24,5]. Some recent works have been done on low Mach fix for non-conservative systems, we refer to [3,2,45] for the Euler equation with gravity or to [35,34] for two-phases flows.…”

“…Many works over the past years have proposed low Mach corrections for single-fluid flows [13,14,18,45,19]. The fix usually amounts to use a centered pressure evaluation at the cell interfaces in the low Mach regime.…”
