Computational Fluid Dynamics Validation Issues in Transition Modeling Academic Article uri icon

abstract

  • Laminar-turbulent transition is highly initial- and operating-condition dependent. Finding careful, archival experiments for comparison is the main validation issue for computational fluid dynamics (CFD) modeling. The CFD formulations validated to date demonstrate that if the environment and operating conditions can be modeled and input correctly, the computations (nonlinear parabolized stability equations and direct numerical simulations) agree quantitatively with the experiments. Future challenges for validation include successful CFD simulations of other available complete databases, CFD leadership in the identification and modeling of the effects of freestream disturbances, CFD leadership in the determination of relevant validation experiments for supersonic and hypersonic flows, careful validation experiments and CFD solutions for complex three-dimensional geometries, and simulations and validations for the high Reynolds numbers of flight.
