A numerical scheme and computing algorithm with a particle tracking method to simulate contaminant migration through heterogeneous flow fields

摘要

PURPOSE: A contaminant movement value mapping method in a complex flow using particle tracking method is provided to simulate contaminant movement in a complex flow in various forms by computer program using the particle tracking method, thereby automatically analyzing movement track and outflow curve according to time about contaminant of various matter property. CONSTITUTION: A data input unit(2) receives input of parameter value and selection value about an analysis object system. A calculation unit(3) determines geological and geometrical structure of flow fields. The calculation unit calculates flow of underground water and a substance movement. A result output unit(4) outputs calculated result in pressure distribution of a flow field, a contaminant movement state according to the time, an outflow curve according to the time and a moving trace of a contaminant.
