Abstract

Flow around an airplane includes various scales; from micro-scale near the surface to macro-scale around the airplane. The macro-scale flow basically determines the surface pressure distribution around an airplane. The microscale flow dynamics also has a significant contribution to such as the skin friction, the flow separations and the aerodynamic noise generation. Current CFD has become a powerful tool to accurately simulate macro-scale flows for designing airplanes. The micro-scale flow simulation, however, is still difficult due to the extremely large difference in the flow characteristic length.
