Multilayer models for hydrostatic Herschel-Bulkley viscoplastic flows
(Elsevier, 2023-06-01)
Starting from Navier-Stokes’ equation we derive two shallow water multilayer models for yield stress fluids, depending on the asymptotic analysis. One of them takes into account the normal stress contributions, making ...

Efficient numerical schemes for viscoplastic avalanches. Part 1: The 1D case.
(Elsevier, 2014)
This paper deals with the numerical resolution of a shallow water viscoplastic flow model. Viscoplastic materials are characterized by the existence of a yield stress: below a certain critical threshold in the imposed ...
