AERODYNAMIC PERFORMANCE OF A WING MOVING CLOSE TO WATER SURFACE

Performance of a WIG vessel (Wing In Ground effect) moving close to the water free surface is an important issue in aerodynamic design of such vessels. Reliable prediction and analysis for wings as well as considering different factors can have significant effects on WIG design. Hence, aerodynamic modeling of wing sections close to the water surface is sutdied and some practical results are derived in this paper. Furthermore, this paper introduces important procedures and numerical implementations for aerodynamic analyses. The accuracy and efficiency of the methods are discussed and the results are persented. In addition the effects of flexible water free surface versus the ground are studied and compared with each other. Some other factors such as viscosity and turbulence are taken into account and their effects are evaluated. Finally some conclusions are summarized based on numerical results.
