Chaotic motion of a harmonically excited square prism modelled as a Duffing oscillator and kept in fluid flow is considered. The fluid dynamic forces contribute additional nonlinear terms to the inherent non-linearity of the system. The harmonically excited oscillator without the fluid fow exhibits

Part 1 presents details of an investigation into the mean loading of smooth, cantilevered circular cylinders immersed in a low-turbulence uniform flow. Experiments were performed in a wind tunnel at a Reynolds number of \(4.4 \times 10^{4}\) for aspect ratios in the range 4 to 30 . Mean surface pres
