Non-Zonal Detached Eddy Simulation coupled with a steady RANS solver in the wall region
Magazine article, 2019
The disadvantage of traditional DES models is that the RANS models in the near-wall region – which originally were developed and tuned for steady RANS – are used as URANS models where a large part of the turbulence is resolved. In the present method – where steady RANS is used in the near-wall region – the RANS turbulence models are used in a context for which they were developed. In this method, it may be worth while to use an accurate, advanced RANS model. The EARSM model is used in the steady RANS solver in the present work. The new method is called N-Z S-DES.
