| Popis: | International audience; This paper presents some developments performed to achieve an accurate and efficient prediction tool for laminar/turbulent transition. These developments involve industrial codes used at Dassault Aviation for the aerodynamics design of military aircraft and business jets. The process is based on a flexible sequence of simulation tools. The issues concerning influence of the numerical solvers, transition onset criteria and the coupling process are described. The influence of intermittency function is also discussed. Results demonstrate the accuracy of the method with emphasis on transition induced by crossflow instabilities. |
