Kajian Numerik Pengaruh Sudut Outward Inclined Sudu terhadap Kinerja Turbin Vertikal Darrieus sebagai Wave Energy Convertion (WEC)

Abstract

In 2024, Indonesia implemented alternative energy regulations through President No. 5 / 2006 to reduce dependence on oil imports, with 31% of the renewable energy targets in 2050. As a maritime nation, Indonesia has significant wave energy potential.. The ongoing research focuses on ocean wave energy utilization using Darrieus's vertical turbine to capture horizontal wave energy in shallow waters. Earlier, WEC models had combined Darrieus and Wells with the configuration of the turbine suu turbine to optimize horizontal and vertical energy conversions of the waves, and this research would develop further Vertical Axis Turbine (VAT) Darrieus with a variation of the corner of the turbine to increase efficiency. The method used involves computational fluid dynamics (CFD) simulations to analyze turbine performance via coeffective of power and coeffective of torque. Research is expected to increase the efficiency of ocean wave conversion in Indonesia.
