Description
Summary:In this study, flow past a rudder with NACA 0012 section has been analyzed using computational fluid dynamics (CFD). A commercial CFD code ANSYS Fluent based on Finite Volume Method (FVM) is used for analysis. At first, two-dimensional rudder section has been analyzed and computed results are validated by comparing with experimental results. Finally, flow past three dimensional rudder has been analyzed. For model development AutoCAD 14 and Rhinoceros 5 have been used. For mesh generation, ANSYS Workbench is used and for flow analysis Fluent is used. In case of two dimensional simulation, Transition k-kl-omega and SST k-omega turbulence models have been implemented to capture turbulent flow past the rudder. Again, in the case of three dimensional simulation, only Transition k-kl-omega turbulence model is used to capture turbulence. The simulation for both two dimensional and three dimensional rudders have been done at different angles of attack ranging from 0 to 20 degree. The computed results have been compared with the experimental results obtained by other researchers and found quite satisfactory.
