CFD Validation Issues for Boundary-Layer Stability and Transition
- View All
Laminar-turbulent transition is highly initial- and operating-condition dependent. Finding careful, archival experiments for comparison is the main validation issue; few exist. The CFD formulations validated to date demonstrate that if the environment and operating conditions can be modelled and input correctly, the computations (nonlinear Parabolized Stability Equations and Direct Numerical Simulations) agree quantitatively with the experiments. A review of validation and verification, challenges of validation, and recent results for 3-D boundary layers and receptivity problems are presented. © 2003 by the American Institute of Aeronautics and Astronautics, Inc.
