| dc.description.abstract | Parametric study using numerical analysis method is used to derive dynamic phase wing shape in this research. FLUENT, commercial CFD code, is used for calculation and RANS (Reynolds time-averaged Navier Stokes) equation is used to analyze turbulent flow near the wings. The gambit program that is the pre-processor of FLUENT generates C-type grid system near the wing and analysis is followed using the standard k-εmodel. Cambered wing that is significant at the lifting force is used as basis. Flow boundary is reduced at the suction side of the wing by changing the existence, location and thickness of slot. Double slot wing shape is derived which is significant during the lifting force characteristics section of the experiment. The results from numerical analysis are verified by comparing between lift and drag force measurement and PIV experiment carried out in CWC(Circulating Water Channel) results. Double slot is applied to otterboard to verify the significance of simulation and field study. Also, flow change is seen at the tip of the three dimensional wing through numerical analysis. Based on these results, detail Tip vortex structure, size and shape of the core can be analyzed. PIV experiment is used to verify the physical aspect. The calculations with the numerical result are matched well with experiment data and computations for the detailed vortex structure are verified by experiment result and analytical solution in this research. | - |
