Computations with k-g Model for Complex Configurations at High-Incidence

Abstract

The two-equation k-g turbulence model, a derivation of the k-w model, with its advantages such as no use of normal-to-wall distance, simple source terms, and straightforward boundary conditions, can be easily applied in complex computational fluid dynamics applications. Transonic flows around the ONERA M6 wing and the NASA TN D-712 wing-fuselage model at angles of attack of 12.5 and 26.2 deg are first used to validate the codes. Then the transonic flows around an F-22-like complete aircraft configuration are numerically simulated at angles of attack from 0 to 48 deg
