CRIS Current Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishIn this paper, we propose a computational approach to estimate the forces acting on a rigid wedge as it impacts a free water surface. The approach is based on the Lattice-Boltzmann Method, wherein the fluid is described as a set of particles streaming and colliding in a discrete time-space environment. Predicted slamming forces are compared with closed-form results based on potential flow and experimental results on drop-tests of rigid wedges.
