| Summary: | In this paper, three dimensional data and behavior of incompressible and steady air flow around a small scale Wing in Ground Effect Craft (WIG) were investigated and studied numerically then compared to the experimental result and also published data. This computational simulation (CFD) adopted two turbulence models, which were k-ε and k-ω in order to determine which model produces minimum difference to the experimental result of the small scale WIG tested in wind tunnel. Unstructured mesh was used in the simulation and data of drag coefficient (Cd) and lift coefficient (Cl) were obtained with angle of attack (AoA) of the WIG model as the parameter. Ansys ICEM was used for the meshing process while Ansys Fluent was used for solution. Aerodynamic forces, Cl, Cd and Cl/Cd along with fluid flow pattern of the small scale WIG craft was shown and discussed. |
