A depth semi-averaged model for coastal dynamics
Antuono, M; Colicchio, Giuseppina; Lugni, Claudio; Greco, Marilena; Brocchini, M (Journal article, 2017)The present work extends the semi-integrated method proposed by Antuono and Brocchini [“Beyond Boussinesq-type equations: Semi-integrated models for coastal dynamics,” Phys. Fluids 25(1), 016603 (2013)], which comprises a ... -
A domain-decomposition strategy for a compressible multi-phase flow interacting with a structure
Greco, Marilena; Colicchio, Giuseppina; Faltinsen, Odd Magnus (Journal article, 2014)The problem of a high-pressure gas cavity and its interaction with surrounding liquid and a close-by structure is examined numerically. Even though this is of interest in many practical applications, here, the focus is on ... -
Analysis of Open-Source CFD Tools for Simulating Complex Hydrodynamic Problems
Siddiqui, Mohd Atif; XU, HUILI; Greco, Marilena; Colicchio, Giuseppina (Chapter, 2020)OpenFOAM (OF) represents an attractive and widely used open-source environment for simulating complex hydrodynamic scenarios with several implemented numerical methods and wide variety of problems it can be applied to. For ... -

Domain Decomposition strategies for modelling survivability conditions of WECs
Colicchio, Giuseppina; Greco, Marilena; Antuono, Matteo (Chapter, 2019) -
Dynamic domain decomposition strategy coupling lattice Boltzmann methods with Finite differences approximations of the Navier-Stokes equations to study bodies in current
Colicchio, Giuseppina; Greco, Marilena; Lugni, Claudio; Faltinsen, Odd Magnus (Chapter; Peer reviewed, 2015)A Domain-Decomposition (DD) strategy is proposed for problems involving regions with slow variations of the flow (A) and others where the fluid features undergo rapid changes (B), like in the case of steady current past ... -
Experimental and Numerical Hydrodynamic Analysis of a Damaged Ship Section In Waves
Siddiqui, Mohd Atif (Doctoral theses at NTNU;2020:361, Doctoral thesis, 2020)In the past few decades, ships have become larger, efficient, durable but the danger of accidental events like grounding, collision etc. continues to be a major issue in ship operations. Following a damage event, a ship ... -
Gas cavity-body interactions: Efficient numerical solution
Colicchio, Giuseppina; Greco, Marilena; Faltinsen, Odd Magnus; Brocchini, Maurizio (Journal article; Peer reviewed, 2015)The paper investigates the interactions occurring between a gas cavity, the surrounding liquid and the nearby structures. In more detail, focus is in the characterization of the various dynamical phases (e.g. “acoustic ... -
Hydroelastic behaviour of a structure exposed to an underwater explosion
Colicchio, Giuseppina; Greco, Marilena; Brocchini, Maurizio; Faltinsen, Odd Magnus (Journal article; Peer reviewed, 2015)The hydroelastic interaction between an underwater explosion and an elastic plate is investigated num- erically through a domain-decomposition strategy. The three-dimensional features of the problem require a large ... -
Hydroelastic response of a submerged structure to an underwater explosion
Colicchio, Giuseppina; Greco, Marilena; Faltinsen, Odd Magnus (Chapter, 2014)The use of composite structures in offshore engineering has revamped the problem of Fluid Structure Interaction (FSI) during underwater blasts because they enhance the FSI effect and increase the shock resistance of ... -
Numerical study of bilge-keel effect on parametric roll and water on deck for an FPSO
Greco, Marilena; Lugni, Claudio; Colicchio, Giuseppina; Faltinsen, Odd Magnus (Chapter; Peer reviewed, 2015)This research activity represents the logical continuation of the work documented in [1] and [2] on water on deck and parametric roll for an FPSO in regular waves. Here the same numerical method, based on a domain-decomposition ... -
Severe Wave-Body Interactions: a Potential-Flow HPC Method and its Strong Domain-Decomposition Coupling with a Level-Set Navier-Stokes Solver
Hanssen, Finn-Christian Wickmann; Colicchio, Giuseppina; Greco, Marilena (Chapter, 2019)The main objective of our ongoing research is to investigate wave loads on and motions of floating bodies in steep waves. For modelling non-linear water-wave and wave-body interaction problems, researchers can use two main ... -
Underwater explosions near marine structures: a Dynamics Fluid Structure Domain-Decomposition strategy
Colicchio, Giuseppina; Greco, Marilena; Faltinsen, Odd Magnus (Chapter, 2016)Historically underwater explosions (UEs) have been investigated for their huge military relevance, but they remain an important issue also for civil marine applications. As an example, UEs can occur near or on oil-gas ... -
