| Summary: | A series of wave tank experiments were recently con-ducted at ´Ecole Centrale de Nantes in France to validate the linear scattering theory used to model hydroelastic in-teractions between regular water waves and sea-ice floes. The experiments discussed in this paper are those involv-ing a single compliant disk. This was set in motion by a controlled incident wave train, generated by a wavemaker. The deflection of the disk was recorded by an optical mo-tion tracking device and the scattered waves around the disk were measured with resistive wave gauges. The disk was only allowed to move in heave, roll and pitch, in addi-tion to the flexural response. The restrictions are in accord with those of the linear model. Aspects of the technical solutions and the measurement devices used in the exper-iments are described. Preliminary comparative numerical versus experimental results are also presented. |
