摘要：
A simulation method for the analysis of the aerodynamic instability of a bluff body is presented. The discrete vortex method is used for separated flow simulation and the Newmark's beta-method is used for response analysis. In the discrete vortex method the free shear layers are approximated by discrete vortices and the body is represented by vorticity distributions. The method is applied to the simulation of the galloping oscillation of a square section.
