Turbulent flow computations of the NASA “trap-wing” high-lift configuration are performed at various angles of attack using a k - ω family of models to assess their capabilities for high-lift design and optimization applications. The four k - ω model variants used are: 1) Wilcox’s 1988 baseline model; 2) variable- β * model consistent with the rapidly strained limit; 3) variable- β * model consistent with the explicit algebraic Reynolds stress model; and 4) Wilcox’s 2006 enhanced model. Subject to the conditions of this test, the variable- β * model consistent with the rapidly strained limit not only performs the best but is also numerically more robust and does not require the use of a production-to-dissipation limiter. Overall, our findings indicate that variable β * makes an important difference. In the proximity of stall, a low-Reynolds-number correction to eddy viscosity may be needed to accurately capture experimental behavior. The results provide much needed insight into the models’ predictive capabilities and identify areas for future k - ω model improvements.
