Abstract

In order to capture wind energy through the wake galloping of cylindrical body, if multiple cylinders can vibrate simultaneously, it would be favorable to capture more wind energy. Based on this idea, a basic wind tunnel experiment has been conducted. In the present experiment, in the wake of a fixed circular cylinder, multiple circular cylinders of the same diameter are supported by coil springs and deployed in tandem alignment. The numbers of spring-supported cylinders are changed from 1 to 3, and the distance between their centers is also changed. As the results, two cylinders or even three cylinders vibrate together. In case that the distance between their centers is double of the cylinder diameter, the two or three cylinders vibrate in bigger amplitude than other wider distance cases though the single cylinder does not reveal wake galloping in such narrow spacing.
