研究了具有常量速度强化因子的两相流动模型,证明了在忽略弥散效应的情况下模型将导致不适定问题,提出如果不考虑任何滞后效应常量速度强化因子将导致聚合物油波前沿上的聚合物聚集.对于IPV(InaccessiblePoreVolume)速度强化效应建立了渗滤模型,该模型中的速度强化因子是水相饱和度的函数,所对应的偏微分方程系统不存在椭圆区域的完全双曲型系统,它不存在常量速度强化因子所固有的稳定性问题
The two-phase flow model with constant velocity enhancement factor is studied. It is proved that the model will lead to the ill-posed problem without considering the dispersion effect. It is proposed that the constant velocity enhancement factor will lead to the polymerization on the front of polymer oil wave without considering any hysteresis effect And the matter aggregation is established. The percolation model is established for the velocity enhancement effect of IPV (InaccessiblePore Volume). The velocity enhancement factor in this model is a function of the saturation of the water phase. The corresponding partial differential equation system does not exist a complete hyperbolic system in the elliptic region. It does not suffer from the inherent stability problems of the constant rate enhancement factor
