Effect of the bottom material capture and the non-Newtonian rheology on the dynamics of turbulent downslope flows

摘要: The paper is devoted to the mathematical modeling of naturally occurring downslope flows, such as snow avalanches, mudflows, and rapid landslides. medium in motion modeled a non- Newtonian fluid, non-Newtonian fluids different types corresponding different-in-nature flows. It taken into account that flows capture slope material entrain it motion. flow assumed be turbulent Lushchik–Pavel’ev–Yakubenko three-equation turbulence model used. so generalized allows for unsteadiness, complicated rheological properties, presence free boundary, mass transfer at lower boundary. effect bottom nonlinear properties on dynamics numerically investigated.
