dc.description.abstract | A three-dimensional multilayer shallow water approach to study polydisperse
sedimentation and sediment transport in a viscous fluid is presented. The fluid is assumed
be loaded with finely dispersed solid particles that belong to a finite number of species that
differ in density and size. The model formulation allows one to recover the global mass and
linear momentum balance laws of the mixture. The model incorporates compressibility of
the sediment and viscosity of the mixture through a viscous stress tensor. As a consequence
of a dimensional analysis applied to the global mass conservation and linear momentum
balance equations, the horizontal components of the compression term and the horizontal
terms of the viscous stress tensor may be neglected. This results in a final model that is
vertically consistent with the classical one-dimensional vertical model. Numerical
simulations illustrate the coupled solids volume fraction and flow fields in various
scenarios and the effect of the compressibility and viscosity terms. Various bottom
topographies give rise to recirculation of the fluid and high solids volume fractions on the
bottom. | es |
