• Analysis of Three-dimensional Sediment Gravity Flow

抄録

A three-dimensional analysis code for the simulation of sediment gravity flows has been developed in the present study by extending a two-dimensional analysis code LIQSEDFLOW developed by Sassa et al. (2003). A set of three-dimensional Navier-Stokes equations and consolidation equation are numerically solved under moving boundary conditions, with consideration of the concurrent evolutions of the flow surface as well as of the internally formed interface between the fluid and solidified zones. For the purpose of identifying the moving interface between the ambient fluid and the liquefied soil, we adopted the volume-of-fluid (VOF) technique (Hirt and Nicholas, 1981). We examined the validity of the proposed analysis procedure against a dam-break problem in which a column of water in air collapses under its own weight. The predicted performance compares favourably with the experimental results of Martin and Moyce (1952) and with the calculated results in terms of LIQSEDFLOW, validating the three-dimensional analysis code developed.
