Experimental Study on Reducing Lateral Force on Circular Cylinder Using Strings
Journal of Ocean Engineering and Technology(2018)
摘要
Recently, it was predicted that the size of offshore markets will grow as gas prices edge up. This paper presents experimental results for using strings as a suppression device on a circular cylinder and discusses the various data. A test model was used to investigate the role of strings by varying the thickness of the strings used to suppress a cylinder’s lateral force taking into account the effect of turbulence promoted. A substantial amount of experimental data were taken from experiments performed on cylinders at Reynolds number up to a maximum value of 105. The suppression of vortex shedding and a lateral force reduction of up to 70% were observed for the cylinder with strings.
