Abstract

This research aims to investigate the potential for optimizing ocean wave energy conversion using an Oscillating Water Column (OWC) device by focusing on the influence of variations in exhaust duct diameter and generator fan angle. Electrical energy, as a major need in Indonesia, demands exploration of renewable energy sources as an alternative to fossil fuels. Experiments were carried out by varying the exhaust duct diameter (5.5 cm, 4.5 cm, 3.5 cm) and generator fan angle (20°, 25°, 30°). The research results show that there is a significant influence of these two variables on OWC performance. The results of wind speed measurements show that with an exhaust channel dimension of 5 cm, the wind speed at an angle of 45° reaches 2.24 m/s, while at angles of 35° and 40° it is 0 m/s. In the same dimensions, increasing the exhaust duct dimensions increases the wind speed, with a dimension of 15 cm providing optimal results at all fan angles. Measuring the fan RPM in the exhaust duct dimensions (5 cm, 10 cm, 15 cm) shows that in the dimensions 5 cm and 15 cm, the fan RPM is 0 at an angle of 35°. Increasing exhaust duct dimensions, especially the 10 cm and 15 cm dimensions, provides a significant increase in RPM at 40° and 45° angles. The 15 cm dimension provides the best performance, especially at 45° angles. Voltage measurements at three angles (35°, 40°, 45°) with varying exhaust channel dimensions show that at dimensions of 5 cm and 15 cm, the voltage is 0 V at an angle of 35°. Increasing the fan angle, especially in the 10 cm and 15 cm dimensions, provides increased voltage. Dimensions 10 cm, at an angle of 45°, reaches the highest voltage of 24.68 V.

排气管尺寸和发电机风扇角度对摆动水柱装置性能的影响

本研究旨在通过重点研究排气管直径和发电机风扇角度变化的影响，探讨利用振荡水柱（OWC）装置优化海洋波浪能转换的潜力。电能是印度尼西亚的主要需求，因此需要探索可再生能源，以替代化石燃料。通过改变排气管直径（5.5 厘米、4.5 厘米、3.5 厘米）和发电机风扇角度（20°、25°、30°）进行了实验。研究结果表明，这两个变量对 OWC 性能有显著影响。风速测量结果表明，排气道尺寸为 5 厘米时，45° 角的风速为 2.24 米/秒，而 35°和 40°角的风速为 0 米/秒。在相同的尺寸下，增加排气道的尺寸会提高风速，15 厘米的尺寸在所有风扇角度下都能达到最佳效果。测量排气管道尺寸（5 厘米、10 厘米、15 厘米）下的风机转速表明，在 5 厘米和 15 厘米尺寸下，风机转速在 35° 角时为 0。增加排气管道的尺寸，尤其是 10 厘米和 15 厘米的尺寸，可显著提高 40° 和 45° 角时的转速。15 厘米的尺寸性能最佳，尤其是在 45° 角时。在三个角度（35°、40°、45°）和不同排气道尺寸下的电压测量结果显示，尺寸为 5 厘米和 15 厘米的风扇在 35° 角时电压为 0 V。增加风扇角度，特别是在 10 厘米和 15 厘米的尺寸上，电压会增加。尺寸为 10 厘米、角度为 45°时，电压最高，为 24.68 伏。
