[Paper] Droplet Formulation Method for Viscous Fluid Injection Considering the Effect of Liquid-Liquid Two-Phase Flow

抄録

The study of fluid analysis includes many examples of particle methods such as SPH and MPS. We have also performed a simulation and compared the results with those of a physical experiment in which viscous fluid was injected from a circular tube into a water tank in order to investigate the droplet formation process. Previous studies used an interfacial tension model that could consider the influence of the other phase in two-phase flow. However, the environment of the physical experiment differed from that of the simulation. Therefore, in this study we performed a viscous fluid injection simulation using the same environment as in the physical experiment. On the basis of the results, we have validated the proposed method by comparing the droplet size and the formation cycle between the physical experiment and the simulation.
