Abstract

In this paper , the amplitude of fluctuating pressure ( Cps) of flow around a single cylinder and a group of three cylinders under two typical wind directions have been studied by wind tunnel testing. Especially, the relations between amplitude and root mean square value ( Cprms) of fluctuating pressure has been found. The amplitudes of fluctuating pressure are in the range of 3~4 times of RMS value in most situations.The large fluctualing pressure appeared on the some part of the rear cylinder, which are caused by the inter-ference of group of cylinders. The relations between Cps and Cprms are out of the range sometimes is due to the strong gap flow at small space ratios.
