• Visualization of Flow around Vehicle using Global Luminescent Oil-Film Skin-Friction Meter

抄録

This paper describes experimental visualization results of flow around a vehicle model using Global Luminescent Oil-Film Skin-Friction (GLOF) meter which can measure both skin-friction distribution and skin-friction vector by detecting luminescent intensity of an oil film on the surface. In particular, we can understand basic fluid structures such as flow separation, reattachment, and vortices and their quantitative locations based on the skin-friction-vector distribution obtained by this technique. The analysis results well capture the characteristics vortex structure in the rear window surface and the vertical vortex generated at the C-pillar. Although a few technical problems are also seen, our results show that GLOF meter is an effective tool for the quantitative visualization of the flow around the vehicle body.
