To improve the applicability of gas-liquid two-phase flow analysis technology, we develop a high-precision method to calculate the gas-liquid interface directly. The Phase Field method with parameter optimization and its advanced Multi-Phase Field method are applied as interface capture methods, and their validity for vertical bubble flow analysis is discussed.
