Unstable Miscible Flow in Heterogeneous Systems

摘要: A method is given for computation of 3-dimensional, unstable, miscible displacement behavior useful heterogeneous systems, as well more ideal conditions. In the method, flow equations are first linearized by a perturbation approach. The basic process separated and solution its readily obtained. remaining problem deviations from caused non-ideal conditions then subjected to numerical analysis. Results obtained use also presented. unique advantage that source variations can be observed. one serious drawback results algebaic complexity approach, need second-order terms retained in calculations interest. Fewer array points available computer time required than would desired. However, these difficulties experiencd with other approaches 3-dimensional problems.
