An analysis tool for boundary layer and correlation-based transition onset assessment on generic geometries

Abstract Today’s CFD simulations tools and the related computational resources provide engineers an enormously high-fidelity design tool to generate enormous aerodynamic aerothermal database, for both laminar turbulent state, in a short time span. However, transitional flow simulation is still its infancy that one needs rely on practical engineering correlations composed of typical boundary-layer parameters. This work describes methodology extract necessary parameters profile information local boundary layer from any vast dataset automatic fashion, allowing apply huge variety best-practise transition prediction relying quantities type 3D geometric body. The validation simple test case flat plate application representative complex use cases with geometry HEXAFLY-INT hypersonic glider demonstrate potential this methodology.
