PRESSURE DISTRIBUTIONS ON TWO CIRCULAR CYLINDERS OF SIDE-BY-SIDE ARRANGEMENTS IN HIGH-TURBULENCE FLOW AT HIGH REYNOLDS NUMBER

This paper presents time-mean as well as fluctuating pressure distributions on single and two identical circular cylinders of side-by-side arrangements under various gap ratios N/d, which were tested in high-turbulence flow (1u=10%) at two high Reynolds numbers Re of 1.95×105 and 6.5 × 10" respectively.The results show that due to the high-turbulence in oncoming flow, the flow around single cylinder at Re = 1.95×105 becomes turbulent separated. The spectrum-analysis shows, that the vortex shedding from the ...
