Numerical Analysis and Flow Visualization for Spin-up in a Half-Cylinder

반 원주 내의 스핀업 유동에 대한 수치해석 및 유동 가시화

In this paper, we report the numerical and experimental results in a half-cylinder. In the numerical computation, we used the zonal embedded grid system. Flow visualization for the spin-up flows was used by PIV. The results show that at left hand side an cyclonic cell moves along a wall and separates into both cells at right hand side.
