Dynamic response, fatigue, and stability issues of a structure are closely related to flow behavior past bluff body structure. Flow the free-end rectangular prism is investigated numerically using Large Eddy Simulation (LES) turbulence model at Re = 22000. The has constant depth (D) width (H) ratio D/H 0.5 for span length variation L (= 10; 7,5; 5,0 2,5H). Effects free end on characteristics showed that pattern, velocity vector, fluid forces component changed. presence closed alteration in wake, which presented graphically this paper. This study suggests critical aspect slender 2,5<L/H<5,0 with 2,5H an unusual among test models. dynamic response affects pattern indicated by region intensity vorticity, hydrodynamic force components, other local components.
