3D Simulation on the Characteristics of Flow around Oscillating Cylinders through the Air-Water Interface

The calculation results on the 3-D fluid motion induced by the oscillating circular cylinders through the air-water interface are presented. The boundary immersed method without tracking the gas-liquid interface by introducing the pressure divided by the fluid density is used. The calculation results were qualitatively verified by comparing them with the experimental studies. The results imply that the three-dimensional flow induced by the oscillating cylinders is extremely complex despite the simplicity of the system.
