Modeling blood flow in networks of viscoelastic vessels with the 1-D augmented fluid-structure interaction system
Francesco Piccioli, Giulia Bertaglia, Alessandro Valiani +1
A noteworthy aspect in blood flow modeling is the definition of the mechanical interaction between the fluid flow and the biological structure that contains it, namely the vessel w…
Uncertainty quantification of viscoelastic parameters in arterial hemodynamics with the a-FSI blood flow model
Giulia Bertaglia, Valerio Caleffi, Lorenzo Pareschi +1
This work aims at identifying and quantifying uncertainties related to elastic and viscoelastic parameters, which characterize the arterial wall behavior, in one-dimensional modeli…
A comparison between bottom-discontinuity numerical treatments in the DG framework
Valerio Caleffi, Alessandro Valiani, Gang Li
In this work, using a unified framework consisting of third-order accurate discontinuous Galerkin schemes, we perform a comparison between five different numerical approaches to th…
Numerical modelling of open channel junctions using the Riemann problem approach
Mohamed Elshobaki, Alessandro Valiani, Valerio Caleffi
The solution of an extended Riemann problem is used to provide the internal boundary conditions at a junction when simulating one-dimensional flow through an open channel network.…
Free surface axially symmetric flows and radial hydraulic jumps
Alessandro Valiani, Valerio Caleffi
Free surface, axially symmetric shallow flow is analysed in both the centrifugal and centripetal directions. Referring to the inviscid steady flow over a flat plate characterised b…
Momentum balance in the shallow water equations on bottom discontinuities
Alessandro Valiani, Valerio Caleffi
This work investigates the topical problem of balancing the shallow water equations over the bottom steps of different heights. The current approaches in the literature are essenti…
