2유체 및 움직이는 고체 사이 연성해석을 위한 수치해석 연구
In this study, a direct numerical simulation is presented for simulating the interactions between two fluids(liquid and
gas) and a moving structure. The fictitious domain method(FDM) is employed to compute fluid structure
interaction(FSI). A high viscosity with average internal velocity is applied to solid region for rigid constraints. Level
contour reconstruction method(LCRM) is integrated into FDM for capturing the moving interface between liquid and
gas. The accuracy of developed numerical method in this study is validated by comparing the results with existing data
from free fall of solid cylinder in 2D fluid container and free fall of a cylinder in a column containing two fluids.
