Abstract
A vast amount of investigations has been carried out for the flow around a circular cylinder. While there are very few were concerned about flow around rectangular cylindrical structures. For flow around a rectangular cylinder, experimental results showed that flow patterns and hydrodynamical forces such as lift, drag and St are strongly dependent on both Reynolds number (Re) and the side ratio of the cylinder’s crosssection. In the range of Re between 102 and 2.0 X 103, the St of a square cylinder shows a slight and continuous change around a constant value. Whereas for flow around a rectangular cylinder with B/A = 2, St varies with Re. Re has little influence on St when it’s greater than 2000 [1,3]. Some researchers have conducted 2-D numerical simulations of flow around a rectangular cylinder in the past, 3-D simulation, however has not been developed. It has been found that a 2-D model can provide accurate results only for Re up to 300 [2,5]. Therefore 3-D simulations are necessary for flow around a rectangular cylinder at higher Re.
