Wave Running on the Oscillating Water Column (OWC) Breakwater Model

Abstract:

It is important to make innovations to design a breakwater model that also functions as a wave energy catcher, a space that creates resonance based on wave characteristics that produce more massive airflow. It is necessary to estimate the maximum wave runup on the OWC breakwater structure to see the runoff that occurs with certain wave conditions and water levels. The efficiency of the OWC breakwater shape and the performance of the OWC breakwater as a wave energy converter are important. In this study to determine the characteristics of waves with various variations of wave period at water depth, which will determine the steepness of the wave (H/L) which is influenced by the wave period (T). Laboratory experimental research method using a wave flume with generated wave characteristics consisting of 5 variations of period (T) i.e. 1.1 seconds, 1.2 seconds, 1.3 seconds, 1.4 seconds, and 1.5 seconds) respectively, with the depth of water (d) used which is 17.5 cm, 21 cm, and 24.5 cm, stroke variations as a wave generator are 4, 5, and 6 respectively. Wave period (T) and water depth (d) strongly influence the resulting wave characteristics in terms of wave height (H) and wavelength (L) values. The relationship between wave steepness (H/L) and period (T) has a difference between the two, with H/L being greater at a depth (d) of 24.5 cm than at depths (d) of 21 cm and 17.5 cm.
