A moment model of shallow granular flows with variable friction laws
Julio Careaga, Qian Huang, Julian Koellermeier
In this work, we develop a modelling framework for granular flows based on the shallow water moment equations on inclined planes. Under the assumption of a polynomial expansion of…

Flux Globalization Based Well-Balanced Path-Conservative Central-Upwind Schemes for Shallow Water Linearized Moment Equations
Yangyang Cao, Qian Huang, Julian Koellermeier +2
We develop second-order path-conservative central-upwind (PCCU) schemes for the hyperbolic shallow water linearized moment equations (HSWLME), which are an extension of standard de…
