Abstract:

The exciting force and pressure distribution for a hemisphere undergoing forced harmonic oscil lations on the free surface were determined. The added mass and damping coefficients were computed from both the integrated pressures and the direct force measurements. There is a certain amount of disagreement between the results of the two methods. The results are compared to the predictions of the linearized hydrodynamic theory as computed by W. R. Porter but, due to the lack of agreement in the experi mental results, quantitative judgements cannot be made. Qualitatively, it is believed that the results are in agreement with the predictions of linearized theory. Author
