Two-Phase Displacement Interface Instability Parameterized Simulation Exploration

The application of fluid dynamics and interface phenomena in multiple industrial domains has been expanding continuously, and the demand for in-depth research has become increasingly prominent. Particularly, the fractal finger phenomenon, which is characterized by its complex multi-physical attributes, poses challenges to traditional experimental and theoretical approaches. This paper primarily proposes a finite element simulation method implemented through COMSOL Multiphysics software, with the aim of conducting a comprehensive analysis of the fractal finger phenomenon. Through the simulation, we are able to delve deeply into the underlying physical mechanisms of this phenomenon, including factors such as fluid dynamics, heat exchange, and interfacial tension. Simultaneously, the highly customizable nature of COMSOL offers us a platform for making detailed comparisons with experimental results, thereby validating the accuracy of the model. The core novelty of this paper lies in the employment of COMSOL to provide an efficient and accurate simulation strategy for the complex fractal finger phenomenon, presenting a new perspective and methodology for research in related fields.
