영문 초록

Particle Imaging Velocimetry (PIV) was adopted to measure velocities in a lid-driven three-dimensional cavity flow. A comparison with experimental results by LDA was made and good agreement was confirmed. The reliability of the present method was validated further by systematic uncertainty analyses. Flow characteristics associated with the cavity flow were discussed in terms of spanwise aspect ratios of 1:1 and 1:3.2 and four Reynolds numbers of 10³, 3.2×10³,5×10³ and 10⁴. The existence of spanwise symmetric flow patterns is characterized.
