INVESTIGATIONS ON IRREGULAR WAVES IN HYDRAULIC MODELS

Karl-Friedrich Daemrich, Wolf-Dietrich Eggert, Soren Kohlhase

Abstract


The first part of the paper deals with some aspects of wave generation by mechanical wave-generators, especially with hydraulic transfer functions for pusher movement of the paddle, and the influences of signal characteristics and analysis methods. In the second part, results of measurements of orbital velocities and pressures in irregular waves are presented, together with some results from theoretical simulation methods in the frequency and time domain, based on linear wave theory.

Keywords
