Abstract
Increasing technology in all corners of the world and the many issues of renewable energy that is environmentally friendly has become the focus of research in several countries to encourage the creation of environmentally friendly alternative energy, one of which is the utilization of wind turbines to produce electricity. The design and development of wind turbines became a topic that caught the attention of many researchers with the above issues. Currently, horizontal axis wind turbine (HAWT) wind turbines have been made, used or developed compared to vertical axis wind turbine (VAWT) types. Therefore, in this Final Project, the writer analyzes and simulates the UAWU type UAWU type VAWT model with two different models using SOLID WORKS 2016 software and ANSYS 15.0 (computational fluid dynamics). The purpose of this final project is to Analyze the effect of blade shape on torque and Analyze the power output of both turbines. The results of analytical calculations and simulations show that design 01 is more optimal compared to design 02, this can be seen from the different torque and wind power values. The value of wind power obtained from design 01 is 4,483 (Watt) and the torque value of 53.88 (Nm), while the wind power generated from design 02 is 3,006 (Watt) and the torque value is 36.13 (Nm). Keywords: VAWT, Computational Fluid Dynamics, RPM, Wind Power, Wind Turbines, Solidwork, VAWT Model, Torque. Semakin meningkatnya teknologi di segala penjuru dunia dan banyaknya isu energi terbarukan yang ramah lingkungan menjadi fokus penelitian di beberapa negara mendorong terciptanya energi alternatif yang ramah lingkungan salah satunya pemanfaatan turbin angin (wind turbine) untuk menghasilkan energi listrik. Perancangan dan pengembangan turbin angin menjadi topik yang menarik perhatian banyak peneliti dengan adanya isu di atas. Saat ini turbin angin jenis horizontal axis wind turbine (HAWT) telah banyak dibuat, digunakan atau dikembangkan dibandingkan dengan jenis vertical axis wind turbine (VAWT). Maka dari itu, pada tugas Akhir ini penulis melakukan analisis dan simulasi model VAWT savonius type U 4 sudu dengan dua model yang berbeda menggunakan software SOLID WORKS 2016 dan ANSYS 15.0 (computational fluid dynamics). Tujuan dari tugas akhir ini adalah Menganalisis pengaruh bentuk blade terhadap torsi dan Menganalisa output daya dari kedua turbin. Hasil dari perhitungan analitik dan simulasi menunjukkan bahwa desain 01 lebih optimal di bandingkan dengan desain 02, hal ini dapat di lihat dari nilai torsi dan daya angin yang berbeda. Nilai daya angin yang di peroleh dari desain 01 adalah 4.483 (Watt) dan nilai torsi 53.88 (Nm), sedangkan daya angin yang di hasilkan dari desain 02 adalah 3.006 (Watt) dan nilai torsi adalah 36.13 (Nm). Kata kunci: VAWT, Computational Fluid Dynamics, RPM, Power Angin, Turbin Angin, Solidwork, Model VAWT, Torque.
