Absorbing wave makers and wide tanks
Salter, Stephen Hugh
MetadataShow full item record
Experiments aimed at generating power from sea waves used models which sometimes reflected waves back to the wave-maker. The difficulty was avoided by changing the wave-maker control system so that it could absorb reflections. A wide tank using a bank of absorbing wave-makers is being used to test more advanced models in seas of controlled angular spread. A crude measure of crest-length can be obtained from measurement of the correlation coefficients between wave-gauges at different separations.
