Numerical Simulation of Oil-water Two-phase Flow Interface Tracking
Journal of Physics: Conference Series, 2023 Abstract The insulation performance of transformer oil has a great connection with the stable operation of power systems, and transformer oil will inevitably be mixed with water and other impurities in the actual operation. To explore the mechanism of the influence of suspended water droplets on the insulation performance of transformer ...

A Fast Algorithm to Simulate Droplet Motions in Oil/Water Two Phase Flow
Procedia Computer Science, 2017 Abstract To improve the research methods in petroleum industry, we develop a fast algorithm to simulate droplet motions in oil and water two phase flow, using phase field model to describe the phase distribution in the flow process. An efficient partial difference equation solver—Shift-Matrix method is applied here, to speed up the calculation coding
