摘要：
Three and two-dimensional simulations of unsteady flows around a rectangular cylinder sectioned object are carried out by means of the IBTD + FS Finite Element technique without the use of a turbulence model. The three-dimensional simulations confirmed that the aerodynamic characteristics of a rectangular object with a side ratio of breadth/ depth (B/D) of 4.0 are in good agreement with the experimental result. We have succeeded in simulating the detailed behavior of the shear layer and the vortex motions around a rectangular sectioned object. The relationship between the structure and aerodynamics of rectangular sectioned objects is also investigated.
