... circular cylinder. The presented model was derived based on Reichardt's wake model for the time averaged wake velocity distribution. It is a combination of using Tollmien's first approximation method and Goldstein's second approximation method. Results indicate that the correction works by this paper do...

..., it is necessary and valuable to investigate the current force and flow field for the pile-group foundation. The classical problem of flow around a circular cylinder has been broadly investigated due to its practical importance in engineering applications. For example, experiments have been carried out by Tritton...

... ABSTRACT This paper presents energy harvesting results by applying vortex-induced vibration (VIV) and galloping excited with a circular cylinder and a triangular cylinder, respectively in a low-speed water flume. The voltage and power were obtained by the energy harvesters under different...

... Abstract Strouhal number is an essential dimensionless quantity for characterizing the vortex shedding frequency of the flow around a bluff body. In this study, the Strouhal number for a near–wall circular cylinder fully immerged in a shear flow was experimentally investigated within...

... and Dalton (1996) studied the vortex shedding from a transversely oscillating circular cylinder in a uniform flow by numerical simulations. The effect of increasing the amplitude of an oscillating cylinder and the Reynolds number value were shown to lower the value of ƒ–ƒ s at which vortex switching...
