COORELATION ANALYSIS OF SURFACE PRESSURE FLUCTUATIONS ON THREE EQUISPACED CYLINDERS

摘要

In this paper, the fluctuating pressure on the surface of three circular cylinders in equispaced arangement were measured simultaneously in the medium subcritical re- gime (Re=3· 10~4). The distributions of their rms values and circumferential correlation were obtained in the spacing range from 1.25 to 6.0. The spatial correlation of pressure of two pressure taps on two different cylinders at the same azimuth was investigated as well.
