Abstract
Experimental results for the drag coefficient and the added hydrodynamic mass coefficient for block bodies, plates, and models of deadweight anchors are presented. A unique method is examined for eliminating noise from an analog signal that relates to the analysis of the recorded forces, and for determining the drag and inertia coefficients in the frequency domain. Results from a regression analysis to determine the drag coefficients and hydrodynamic mass coefficients are presented and compared to the other method employed. The experiments show that both the added mass and the drag coefficients are dependent upon the ratio of the amplitude of the water particle excursion to the major dimension of the body.
