Abstract

This paper treats the analysis of aerodynamic response characteristics of a rectangular cross section (the proportion between the long side and the short side was 4:1) by computational fluid dynamics (CFD). The Improved Balancing Tensor Diffusivity/Fractional Step (IBTD/FS) finite element formulation was applied to a CFD method and two dimensional calculations were performed. The Spalart-Allmaras (SA) model was applied to a turbulent model, and the Arbitrary Lagrangian-Eulerian (ALE) method was applied to a dynamic analysis. Aerodynamic force and displacement were calculated by CFD. In addition, the range of wind velocity in which a characteristic aerodynamic phenomenon occurs was investigated. The animation of the flow area in the velocity was made to be observed on the causes for the occurrence of characteristic phenomena.
