Abstract
Abstract: An assessment of the SST k−ω turbulence model is made using different freestream values for k and ω. Flows over an ogive cylinder and the Onera M6 wing are used as test cases. Main result: It is found out that in some situations a solution is significantly affected by the free-stream turbulence quantities. A modification is made to the FINFLO code in order to remove the effect of the free-stream values.
