Characteristic Features of Modeling Multiphase Flows in the Hele-Shaw Cell
摘要
A two-phase fluid flow in a Hele–Shaw cell is considered. A series of experiments on stable displacement from the cell is described. A discrepancy between experimental data and analytical solutions based on the generally accepted mathematical model for describing flows in a Hele–Shaw cell is shown. A modified mathematical model with a correcting resistance coefficient determined empirically is proposed. The new semiempirical model provides good agreement with experimental data. The results of numerical modeling of unstable flow in a Hele–Shaw cell are also presented.
