My key research interests are: marine hydrodynamics, computational fluid dynamics, non-linear free-surface and interface flows, wave-structure interactions, hydroelasticity. The general knowledge in marine hydrodynamics, gained especially through the PhD studies, was applied to carry on several analyses. Main topics of investigation are related to free-surface flow problems relevant for ship hydrodynamics, offshore structures and coastal engineering, focusing on resistance, manoeuvring and seakeeping. Major contributions are in theoretical and numerical modelling, complemented by experimental studies and related analyses. Within the theoretical framework: local high-speed solutions based on Wagner-type and similarity solutions have been investigated and coupled with numerical-based solvers. Within the numerical framework: a 2D fully nonlinear Boundary Element Method (BEM), a 2D shallow-water approximation, a 3D weakly-nonlinear seakeeping solver, 2D and 3D Domain-Decomposition (DD) strategies, have been developed. The DD strategies coupled: 1) 2D global linear seakeeping analysis with 2D inner nonlinear BEM analysis, 2) 2D global nonlinear BEM analysis with a 2D inner Navier-Stokes analysis based on a Finite Difference solver and a color-function technique for the air-water interface, 3) 3D global weakly-nonlinear seakeeping analysis with a 2D inner shallow-water approximation. The DD development required the gain of a deep knowledge of the involved methods. Cooperation was supplied to the development and application of 2D and 3D SPH solvers for the study of hydrodynamic problems. Within the experimental framework: design, cooperation to the tests, and data analysis, were performed in connection with water-on-deck model tests involving video-recording, wave-elevation and load measurements. Present research concerns the development of a 3D DD strategy combining a potential-flow seakeeping solver with a Navier-Stokes method for violent water-vessel interaction problems.
