Study of characteristics of inertia and viscous flow regions by means of dam break flow with finite volume.

抄録

In this study, the characteristics of inertia and viscous regions of shallow flow are investigated by means of dam break flow with finite volume occurring in a smooth rectangular channel. Inviscid fluid and viscous fluid, comprising of Newtonian and non-Newtonian are studied theoretically and similarity solutions describing both inertia and viscous regions are derived. Theoretical findings are verified with two numerical models: a depth averaged model and a Lagrangian grid-less model (MPS or Moving Particle Semi-Implicit).
