开发了一个用于地下水系统污染分析和修复的组分模拟器。同时流动的三个流体相（水，气体和有机）进行建模。可以模拟任意数量的有机和无机组分的相间分配和运输。相密度是压力和相组成的函数。该模型包括几个数值选项，从一阶上游加权的全隐式到压力隐式，饱和度显式和浓度三阶上游加权。该模型进行了验证，在可能的范围内与多相流和污染物传输的简化情况下的解析解。在模型中使用的各种数值选项的准确性和效率进行了说明。
A compositional simulator is developed for application to the analysis of contamination and remediation of groundwater systems. Simultaneous flow of three fluid phases (water, gas, and organic) is modeled. Interphase partitioning and transport of an arbitrary number of organic and inorganic components can be simulated. Phase densities are functions of pressure and phase composition. The model includes several numerical options, ranging from fully implicit with first-order upstream weighting to implicit in pressure, explicit in saturations and concentration with third-order upstream weighting. The model is verified to the extent possible with analytical solutions for simplified cases of multiphase flow and contaminant transport. The accuracy and efficiency of the various numerical options used in the model are illustrated.
