Inline and transverse forces on a tube array in tandem with waves
In a wave tank test with a vertical tube array arranged in line with the wave direction, forces on the tubes as well as small instrumented sections of the tubes were measured. The inertia, drag and lift coefficients are determined from the forces on the instrumented sections. Mean curves are drawn through the scatter of the experimental points and presented as functions of the Keulegan-Carpenter number and the tube spacing. The total forces on the tubes based on the mean curves are correlated with the measured total forces. The effect of blocking of waves by tubes one behind the other and various tube spacings upon the forces on the tubes are shown. It is found that the inertia and drag coefficients generally decreased with decreased spacings due to shielding while the lift coefficient increased.
