论文摘要
使用不连续多项式近似值的数值方法是为了求解用可溶性表面活性剂的两个不混溶的流体的相位模型。该方案在平衡处恢复了Langmuir的吸附等温线。旋律分解，流经圆柱体并流过一系列孔喉的模拟显示出有或没有表面活性剂的流动动力学。最后，数值方法用于模拟通过Micro-CT成像获得的Berea砂岩的孔隙空间中的流体流。
A numerical method using discontinuous polynomial approximations is formulated for solving a phase-field model of two immiscible fluids with a soluble surfactant. The scheme recovers the Langmuir adsorption isotherms at equilibrium. Simulations of spinodal decomposition, flow through a cylinder and flow through a sequence of pore throats show the dynamics of the flow with and without surfactant. Finally the numerical method is used to simulate fluid flows in the pore space of Berea sandstone obtained by micro-CT imaging.
