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 well-balanced finite difference WENO scheme for shallow water flow model
Gang Li, Valerio Caleffi, Zhengkun Qi
In this paper, we are concerned with the shallow water flow model over non-flat bottom topography by high-order schemes. Most of the numerical schemes in the literature are develop…
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…
Mathematical study of linear morphodynamic acceleration and derivation of the MASSPEED approach
Francesco Carraro, Davide Vanzo, Valerio Caleffi +2
Morphological accelerators, such as the MORFAC (MORphological acceleration FACtor) approach, are widely adopted techniques for the acceleration of the bed evolution, which reduces…
