| Summary: | The flow over objects such as high-rise buildings, marine risers, bridges, cooling towers, chimneys and tube bank in heat exchangers are encountered extensively in engineering applications. These objects, which under normal circumstances, usually create a massive wake region downstream, are called bluff bodies. Motion of objects such as submarines, ships and cars through fluids are examples of a pivotal role of such bluff objects in industrial applications. Thus, its major importance in a multitude of applications such as civil, wind engineering and technical problems associated with energy conversion and structural design. This type of flow often contains many complex phenomena such as separation, wake flow, vortex shedding, curved free shear layers, dominant large scale structure and high turbulence. |
