説明

Interference effect between two oscillating circular cylinders in still water is experimentally investigated. The array of two circular cylinders with the same diameter is placed at the angle of 0゜,30゜,45°and 90゜ to the direction of motion. The spacing between the cylinder centers was varied from 1.2 diameters to 7 diameters. Drag and added mass coefficients, which are analyzed the experimental data by Fourier Analysis, are presented as the functions of the K_c number and the spacing of two circular cylinders. Lift coefficient and its frequency in occurrence are also obtained to show that the lift force decreases a little with decreasing the spacing and that the lift frequency is independent of the spacing.
