수평 보텍스 링의 동적 특성에 대한 3차원 수치해석 및 실험
Three Dimensional CFD and Experiment Study on the Dynamic Characteristics of a Horizontal Vortex Ring
초록
In this paper, we report the numerical and experimental solutions of the dynamic characteristics of a vortex ring in a circular cylinder generated by impinging a fluid blob from a hole on the bottom wall of the cylinder. We managed to visualize successfully the flow pattern shown on the vertical and horizontal planes by using a specially designed optical apparatus. Results of three-dimensional computation for the flow are shown to be in a satisfactory agreement with the experimental ones. We also report the experimental results which show a breaking of the axi-symmetric pattern after the vortex touches the free surface.
