内容記述 | In this study, the reliability of OpenFOAM has been confirmed through the incompressible fluid analysis around the NACA0012 airfoil and comparing the result of the analysis between Ladson's experiment and Gregory's experiment. Reynolds number of the flow field is Re =6.0×10(exp 6) and dimension of the analysis flow field is quasi-two-dimensional flow and two-dimensional flow. "simpleFoam", Steady-state solver for incompressible turbulent flow based on the SIMPLE method, is selected as a solver, "Spalart-Allmaras model" is selected as a turbulence model. Free stream boundary conditions of the Spalart-Allmaras model utilized to OpenFOAM are work variables (wave dash nu) and turbulent kinematic viscosity (nu (sub t)). Work variables are (wave dash nu) = 1/10 (nu) , 10 (nu) and 1000 (nu). Analysis mesh is generated by blockMesh and snappyHexMesh for the quasi-two-dimensional analysis, and blockMesh for the two-dimensional analysis. As a result of quasi-two-dimensional analysis, lift and drag coefficient curves are not match to the experiment and stall appears with small angle of attack. The reason is because there is no boundary layer mesh in the quasi-tow-dimensional model. As the result of two-dimensional analysis, NACA’s mesh and blockMesh get close value to the Ladson's experiment and Gregory's experiment. Especially, pressure coefficient calculated by blockMesh model is match to the experiment result. | |||||
