This article investigates effect of mesh distribution in wakes and distant flow-fields from an airplane on resulted flow phenomena when performing RANS CFD simulation. Heretofore, mesh distribution in those flow-fields is rather coarse. It is not sufficient for grasping accurate wake phenomena which are important for obtaining aerodynamic coefficient by wake integration as well as evaluating wake turbulence effect on others. The investigation is conducted regarding three subjects. The first one is mesh distribution in the vicinity of far-field boundaries of a computational domain. The second is to enlarge a computational domain, while the other is mesh distribution on downstream field of airplane. Through the investigation, several useful clues have been obtained for attaining good flow resolution in those fields by CFD.
