Numerical Simulation of Failure Behavior of Granular Debris Flows Based on Flume Model Tests

In this study, the failure behaviors of debris flows were studied by flume model tests with artificial rainfall and numerical simulations (PFC(3D)). Model tests revealed that grain sizes distribution had profound effects on failure mode, and the failure in slope of medium sand started with cracks at crest and took the form of retrogressive toe sliding failure. With the increase of fine particle...

Numerical Simulation of Rayleigh-Taylor Instability by Multiphase MPS Method

The Rayleigh-Taylor instability problem is one of the classic hydrodynamic instability cases in natural scenarios and industrial applications. For the numerical simulation of the Rayleigh-Taylor instability problem, this paper presents a multiphase method based on the moving particle semi-implicit (MPS) method. Herein, the incompressibility of the fluids is satisfied by solving a Poisson Pressu...

FLOW BEHAVIOR OF MOLTEN METAL IN ALUMINUM LFC PROCESS

The effects of gating system and pattern geometry on the metal flow in the lost foam casting (LFC) process have been investigated using glass covered mold and video recording system. Unlike convectional casting process, the type of the gating system showed little effect on fillability in lost foam, but pattern thickness had large effect on mold filling. The mold filling behavior seems to be con...
