Item type:Publication, Access status: with files , Numerical noise prediction in multi-phase flows, a mesh sensitivity study(Norwegian University of Science and Technology, Department of Marine Technology, 2024-04-04); ; The paper reports a mesh sensitivity study of a NACA 662 − 415 elliptic wing hydro-acoustic simulations. The numerical calculations were performed using a DDES approach with a k − ω SST turbulence model and a VOF Schnerr-Sauer Cavitation model. To compute the radiated noise, Ffowcs-Williams and Hawkings (FW-H) acoustic analogy was used, employing a Farassat 1A formulation and computing the quadrupole noise term. The results show good convergence for lift, drag and the linear terms of radiated noise, while the quadrupole volume term presents a slower convergence. Overall, the results compare well with the experiments.Publicationtype: Conference Paper28 115
