COMPLIANT WATER WAVE ABSORBERS - PART 2.

Abstract

The report which is a continuation of 'Compliant Water Wave Absorbers' (AD-624 508) by the same author, is concerned mainly with theoretical and experimental investigations of a sliding wedge type water wave absorber at the end of a channel. A re-examination of the theory of the stability of linear active wave absorbers is carried out and some errors in symbols and signs appearing in the prior work are corrected. Also, a simplified process for evaluating the stability of a wave absorber is evolved and implemented by means of a computer program. Experimental investigations show certain practical difficulties encountered with sliding wedge type absorbers and it is concluded that the hinged paddle type absorber is more practical if steps are taken to reduce the effects of standing wave resonances in the space behind the paddle.
