摘要: The aim of this study is to investigate and compare the wake behind fin foam covered circular cylinders by mean Particle Image Velocimetry (PIV). Two different arrangements were examined namely single cylinder a single-row bundle three identical in cross flow. experiments are conducted for range Reynolds numbers from 1500 8000 based on inner diameter air velocity upstream bundle. two dimensional planar PIV results as well POD analysis show important effects inlet velocity, covers, arrangement, being an isolated or bundled, wake. considerable increase size using instead tube. can be used accurate boundary condition model flow field past such
