dc.description.abstract | We fundamentally study on vortical flow behind the three-dimensional circular wing. For more improved hydrodynamic analysis, we employ a B-Spline-based higher-order panel method including a nonlinear wake roll-up mechanism. Using the present numerical method, we can well-predict the contraction and position of vortex cores just with the longitudinal trailing wake shapes. Numerical results are compared with the experiments from a cavitation tunnel in Chungnam National University (CNUCT). Observations of the vortical flow behind the circular wing and inception dynamics of tip vortex cavitation are obtained using high speed cameras and SIV(Shadow Image Velocimetry). In addition, we measure pressure fluctuations above the circular wing which are closely related with vortical flow noise. | - |
