(EDP Sciences, 2020-01-28)
Article
Open Access
Covenantee: Università di PisaContext. High-resolution spectroscopy has revealed large concentrations of CNO and sometimes other intermediate-mass elements (e.g., Ne, Na, Mg, or Al, for ONe novae) in the shells ejected during nova outbursts, suggesting ... -
2d river flood modelling using Hec-ras 5.0
(Universitat Politècnica de Catalunya, 2016-06-20)
Bachelor thesis
Open AccessFlooding may occur as an overflow of water from water bodies, such as a river, lake or ocean, in which the water overtops or breaks levees, resulting in some of that water escaping its usual boundaries. Floods also occur ... -
3D Hydrodynamical simulations of helium-ignited double-degenerate white dwarf mergers
(2022-06-01)
Article
Open AccessThe origins of Type Ia supernovae (SNe Ia) are still debated. Some of the leading scenarios involve a double detonation in double white dwarf (WD) systems. In these scenarios, helium shell detonation occurs on top of a ... -
A FEM fluid-structure interaction algorithm for analysis of the seal dynamics of a Surface-Effect Ship
(2015-10)
Article
Open AccessThis paper shows the recent work of the authors in the development of a time-domain FEM model for evaluation of the seal dynamics of a surface effect ship. The fluid solver developed for this purpose, uses a potential flow ... -
A general stabilized formulation for incompressible fluid flow using finite calculus and the finite element method
(2003-03)
Research report
Open AccessWe present a general formulation for incompressible fluid flow analysis using the finite element method (FEM). The necessary stabilization for dealing with convective effects and the incompressibility condition are introduced ... -
A non-linear finite element method on unstructured meshes for added resistance in waves
(2018-06-15)
Article
Open AccessIn this work a finite element method is proposed to solve the problem of estimating the added resistance of a ship in waves in the time domain and using unstructured meshes. Two different schemes are used to integrate the ... -
A numerical study on hydraulic fracturing problems via the proper generalized decomposition method
(2020-02-01)
Article
Open AccessThe hydraulic fracturing is a nonlinear, fluid-solid coupling and transient problem, in most cases it is always time-consuming to simulate this process numerically. In recent years, although many numerical methods were ... -
A review of flood impact assessment approaches for underground infrastructures in urban areas: a focus on transport systems
(2020-06)
Article
Open AccessFlooding events can produce significant disturbances in underground transport systems within urban areas and lead to economic and socioenvironmental well-known consequences, which can be worsened by variations in the ... -
Advanced numerical methods for shallow water simulations
(Universitat Politècnica de Catalunya, 2023-07-18)
Bachelor thesis
Open AccessThis project is about the usage of Runge Kutta methods in Shallow Water simulations. This is not widely used in any case as other methods such as Euler or Adam Bashforth. Runge Kutta is a predictive method that is believed ... -
An improved updated Lagrangian SPH method for structural modelling
(Springer, 2023-11-27)
Article
Restricted access - publisher's policyThis paper presents a set of novel refined schemes to enhance the accuracy and stability of the updated Lagrangian SPH (ULSPH) for structural modelling. The original ULSPH structure model was first proposed by Gray et al. ... -
An SPH Formulation for Incompressible Newtonian Free Surface Flows
(Universitat Politècnica de Catalunya, 2013-06-28)
Master thesis
Open AccessThe meshless method Smoothed Particle Hydrodynamics (SPH) is one of the primarily developed numerical methods in the meshless methods family. It has been proven to work well with problems of free surface fluid flows. For ... -
