内容記述 | Proper Orthogonal Decomposition (POD) and Dynamic Mode Decomposition (DMD) are to be applied to the flow near the leading edge and wake of a 2-D rectangular prism. Flow around 2-D rectangular prisms with B/D=1 and 8 are visualized by PIV and its 2-D velocity vector field is decomposed by POD and DMD. The prism is set in still condition in smooth flow and in grid turbulence in wind tunnel. Flow field in xy or xz plane (x: chord-wise, y: span-wise, z: vertical (normal to side surface) directions) is visualized using laser sheet and smoke under Re=2.5 to 3.75e3 with respect to D. DMD was applied to the wake behind a 2-D square prism at first examined. The periodicity in wake is clearly extracted by POD and DMD. Flow in a separation bubble is then observed through POD and DMD, which illuminate 3-dimensional flow characteristics and may connect with the increase of span-wise correlation of aerodynamic force. | |||||
