Layer-averaged approximation of Navier–Stokes system with complex rheologies
Fernández-Nieto, E.D.; Garres-Díaz, José (EDP Sciences, 2023)In this work, we present a family of layer-averaged models for the Navier–Stokes equations. For its derivation, we consider a layerwise linear vertical profile for the horizontal velocity component. As a particular case, ... -
Multilayer models for hydrostatic Herschel-Bulkley viscoplastic flows
Fernández-Nieto, E.D.; Garres-Díaz, José; Vigneaux, P. (Elsevier, 2023)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 ... -
Multilayer Shallow Model for Dry Granular Flows with a Weakly Non-hydrostatic Pressure
Escalante, Cipriano; Fernández-Nieto, E.D.; Garres-Díaz, José; Mangeney, Anne (Springer, 2023)The multilayer model proposed in this paper is a generalization of the multilayer non- hydrostatic model for shallow granular flows (Fernández-Nieto et al in Commun Math Sci 16(5):1169–1202, 2018. https://doi.org/10.43 ... -
Non-hydrostatic layer-averaged approximation of Euler system with enhanced dispersion properties
Escalante, Cipriano; Fernández-Nieto, E.D.; Garres-Díaz, José; Morales de Luna, Tomás; Penel, Yohan (Springer, 2023)A new family of non-hydrostatic layer-averaged models for the non-stationary Euler equations is presented in this work, with improved dispersion relations. They are a generalisation of the layer-averaged models introduced ...
