| Popis: |
Results of measurements of surface pressure and of velocity field made on a full-scale 6 mrncube in natural wind are reported. Comparisons are made with results from boundary-layer wind-tunnelrnstudies reported in the literature. Two flow angles are reported; flow normal to a face of the cube (the 0 orncase) and flow at 45 o . In most comparisons, the spread of wind-tunnel results of pressure measurementsrnspans the full-scale measurements. The exception to this is for the 0 o case where the roof and side-wallrnpressures at full-scale are more negative, and as a result of this the leeward wall pressures are also lower.rnThe cause of this difference is postulated to be a Reynolds Number scale effect that affects flow reattachment.rnMeasurements of velocity in the vicinity of the cube have been used to define the mean reattachmentrnpoint on the roof centre line for the 0 o case, and the ground level reattachment point behind the cube forrnboth 0 o and 45 o flow. Comparisons are reported with another full-scale experiment and also with wind-tunnelrnexperiments that indicate a possible dependency on turbulence levels in the approach flow. |
