The purpose of this thesis is to develop numerical methods for optimization, control and shape design in computational fluid dynamics, more precisely in haemodynamics. The application studied is related with the shape optimization of an aorto-coronaric byp ...
With the development of numerical tools used to simulate fluid-structure interactions phenomena, investigations on hydrodynamic damping are now more accessible and the studied cases are more flexible. The aim of the present study is, at first, to analyze t ...
A numerical method for the simulation of the motion of a glacier in two and three dimensions is presented. Glacier ice is treated as an incompressible viscous fluid. The model equations are based on mass, momentum, energy conservation and a specific rheolo ...
In the past few years, Computational Fluid Dynamics (CFD) has become an essential tool in the design and optimization of racing sailboats and in particular America's Cup yachts. The prevalent role of CFD in the design process is demonstrated by the number ...
We address the numerical simulation of fluid-structure interaction problems characterized by a strong added-mass effect. We propose a semi-implicit coupling scheme based on an algebraic fractional-step method. The basic idea of a semi-implicit scheme consi ...
Sound or acoustic tomography is a type of inverse problem. The idea of estimating physical quantities that influence sound propagation by measuring the parameters of sound propagation has proven to be successful in several practical domains, including medi ...
In this Note we propose a stabilized explicit coupling scheme for fluid-structure interaction based on Nitsche's method. The scheme is stable irrespective of the fluid-solid density ratio. Numerical experiments show that optimal time accuracy can be obtain ...
The motion of a two-dimensional glacier is considered. At each time step, given the shape of the glacier, ice is modelled as an incompressible non-Newtonian fluid and a non-linear elliptic problem has to be solved to obtain the horizontal velocity field. T ...
The subject of this thesis is the numerical simulation of viscous free-surface flows in naval engineering applications. State-of-the-art numerical methods based on the solution of the Navier-Stokes equations are used to predict the flow around different cl ...
The aim of this work is to provide mathematically sound and computationally effective tools for the numerical simulation of the interaction between fluid and structures as occurring, for instance, in the simulation of the human cardiovascular system. This ...
