WebApr 13, 2024 · Bluff bodies are prone to vortex-induced vibration (VIV), a phenomenon that causes these structures to obey a cyclic motion, both in the direction of the incoming flow and (more intensely) in the transverse direction (Williamson and Govardhan, 2004 55.Williamson, C.

WebA bluff body is defined as that body whose surface is not aligned with the stream-lines, when placed in the flow. Therefore, the body offers lesser resistance in terms of Viscous … WebApr 1, 2024 · This study reviews the available literature on the flow control of vortex shedding behind bluff bodies and its destructive wake through the modification of the geometry of the bluff body.

WebThe square-back bluff body model used by [12] was also employed in the present study. This configuration creates a large wake behind the body and experiences clean separation at the trailing edges of the model [1-19]. In order to modify the near wake flow structures a drag reduction device similar to that of [2] was installed at the base of the ... WebBluff body hydrodynamics is a general term that may be used in the naval field to describe the study of hydrodynamics of floating and fixed structures that generate significant regions of separated flow. Clearly bluff body aerodynamics and bluff body hydrodynamics are closely related but in the naval context the presence of an air/water ...
