This analysis is carried out by comparing the numerical velocity field to the experimental visualizations, obtained through liquid crystals. All of the numerical solvers give results consistent with the physical limits of the equations that they discretized.786205 bytesapplication/pdfenCopyright:1998 American Institute of Aeronaut and AstronautAerodynamic characteristicsNavier-stokes solverReynolds-averaged equationsAerospaceEngineeringArticleLombardi, G., Salvetti, M., & Morelli, M.
