Abstract

Sail dan casing pada kapal selam U209/1300 dapat memengaruhi hambatan hidrodinamika selama beroperasi dalam kondisi menyelam penuh. Penelitian ini menganalisis pengaruh keberadaan casing dan variasi posisi sail menggunakan metode Computational Fluid Dynamics (CFD) pada kecepatan 5, 10, dan 15 knot dengan model turbulensi RANS k-ω SST. Delapan konfigurasi dianalisis, meliputi bare hull serta variasi posisi sail pada posisi standar, 10% L ke depan, dan 10% L ke belakang, baik dengan maupun tanpa casing. Pengaturan numerik divalidasi menggunakan model DARPA SUBOFF dan menghasilkan galat koefisien hambatan sebesar 1,4% dibandingkan dengan data eksperimen. Hasil simulasi menunjukkan bahwa hambatan meningkat seiring dengan peningkatan kecepatan dan penambahan komponen eksternal. Casing meningkatkan luas permukaan basah, sedangkan sail memengaruhi distribusi tekanan di sekitar lambung. Posisi sail standar menghasilkan hambatan terendah di antara variasi posisi sail, baik dengan maupun tanpa casing. Oleh karena itu, konfigurasi SSC-STD dianggap sebagai konfigurasi operasional terbaik karena tetap menggunakan sail dan casing serta menghasilkan hambatan yang lebih rendah dibandingkan dengan konfigurasi sail di posisi depan dan belakang.

The sail and casing of the U209/1300 submarine can affect its hydrodynamic resistance during submerged operation. This study analyzes the effects of casing presence and sail position using Computational Fluid Dynamics (CFD) at speeds of 5, 10, and 15 knots with the RANS k-ω SST turbulence model. Eight configurations were evaluated, including the bare hull and sail variations at the standard, 10% L forward, and 10% L aft positions, both with and without casing. The numerical setup was validated using the DARPA SUBOFF model, with a drag coefficient error of 1.4% compared with experimental data. The results show that resistance increases with speed and the addition of external components. The casing increases the wetted surface area, while the sail influences the pressure distribution around the hull. The standard sail position produces the lowest resistance among the sail-position variations, both with and without casing. Therefore, SSC-STD is considered the best operational configuration because it retains the sail and casing while producing lower resistance than the forward and aft configurations.
