- Mixed Fluid, Two-Phase Wedge-Sliding Model, Phase Drift
Most multiphase flow models use viscosity as an important parameter, however, the viscosity of mixed fluid sometimes is unavailable or difficult to measure especially in small-scale flowing condition. In order to solve this problem, a two-phase wedge-sliding model is developed in this paper and this model is non-viscosity dependent. Two variables of Drift-inhibition angle and expasion-inhibition angle were defined and their expressions were deduced from the model, which can well index the phase-drift trend of mixed fluid. The study also found that there is an optimal ratio in the ingredients design of mixed fluid and mixed fluid can only be stable when the volume ratio of heavier phase is smaller than this optimal value.
