Numerical experimental comparison of mudflow by smoothed particle hydrodynamics (SPH)

Abstract Flow-like landslides are a serious geologic hazard that can cause life and property loss all over the world. Mudflow is kind of debris flow has been classified as non-Newtonian flow. The Smoothed particle hydrodynamics method (SPH) powerful tool for modeling fluids, such debris/mudflows, which be described in terms local interactions their constituent parts. In this paper, Herschel-Buckley rheology model SPH used to simulate free-surface mudflow under gate. run-out distance velocity during time calculated with numerical simulation compared laboratory result. Our results indicate rate increase viscosity computer more than experimental it because friction assumed zero. simulation, exactly zero but model, could measured Finally, Abacus had good result protection viscosity.
