This paper questions and improves commonly used guidelines for modelling a tube bundle in cross-flow at ReD = 3.4 · 104 1.1 105. Especially, when the locations of flow separation are high interest. A major conclusion this is that near-wall (y+ < 5) preferable use wall functions with y+ > 5 should be avoided relation to behind tubes cross-flow. CFD may simplified symmetric or periodic boundary conditions account full geometry. The present work reveals periodicity vorticity formation...
