Abstract
This paper presents the comparison of numerical simulation results and wind tunnel experiment for compound WIG's wing. Numerical simulation was performed in the ANSYS Fluent software. The choice of the turbulence model and the computational mesh parameters, including the resolution of the boundary layer, are substantiated. Comparison of the results of the experiment and numerical simulation showed good convergence for middle density mesh about 7 million cells and first layer height 0.0001 m. Additional study for k-ε realizable and k-ω SST turbulence models was done. Its result founded much efficiency k-ε realizable model than k-ω SST turbulence models for compound WIG's wing. Numerical simulation takes less time and ensures the same accuracy. The results can be argued that the selected parameters of numerical simulation can be used to obtain the aerodynamic characteristics of various layout solutions for "type C" WIG craft.
