Abstract

Penelitian ini memodelkan tiga buah rigid sail dalam empat macam konfigurasi (A1, B1, B2, dan C1) pada model kapal tiga dimensi (3D) untuk menyertakan susunan layar dan variasi angle of attack 0°, 15°, dan 30° dengan kecepatan angin apparent 5 knot dan 20 knot. Aliran udara di sekitar layar dan kapal dianalisis, dan heeling force serta driving force (FR) diukur. Susunan layar kemudian diisolasi dari kapal dan dianalisis menggunakan metode Computational Fluid Dynamics (CFD). Diasumsikan bahwa kecepatan kapal yang ingin dicapai adalah 12 knot dan berat dari rigid sail yang kurang dari 3% dari berat kapal diabaikan, memungkinkan penentuan gaya dorong propulsi sepanjang arah gerakan kapal. Hasil penelitian menunjukkan bahwa pada kecepatan angin 5 knot, semua konfigurasi tidak dapat memberikan Kecepatan yang cukup untuk mengatasi Resistance kapal. Namun, pada kecepatan angin 20 knot, semua konfigurasi mampu memberikan dorongan yang cukup dengan konfigurasi C1 menghasilkan kecepatan tertinggi yaitu 5,66 knots pada sudut serang 30°. Jumlah dan posisi layar memengaruhi hasil kecepatan kapal, dengan konfigurasi B2 memberikan sedikit gaya interaksi antar layar dan menghasilkan kecepatan yang lebih besar dibandingkan B1

This study models three rigid sails in four configurations (A1, B1, B2, and C1) on a three-dimensional (3D) ship model to include sail arrays and angle of attack variations of 0°, 15°, and 30° with apparent wind speeds of 5 knots and 20 knots. The airflow around the sails and the ship is analyzed, and the heeling force and driving force (FR) are measured. The sail array is then isolated from the ship and analyzed using the Computational Fluid Dynamics (CFD) method. It is assumed that the desired ship speed is 12 knots and the weight of the rigid sails which is less than 3% of the ship's weight is neglected, allowing the determination of the propulsion thrust along the direction of the ship's motion. The results show that at a wind speed of 5 knots, all configurations cannot provide sufficient Speed ​​to overcome the Ship's Resistance. However, at a wind speed of 20 knots, all configurations are able to provide sufficient thrust with the C1 configuration producing the highest speed of 5.66 knots at an angle of attack of 30°. The number and position of sails affects the resulting speed of the ship, with the B2 configuration providing less interaction force between the sails and producing greater speed than the B1
