Abstract

Studi ini menyelidiki konfigurasi chine dan transversed step hull yang menguntungkan dibandingkan model konvensional, menggunakan metode Computational Fluid Dynamics (CFD) yang memiliki akurasi yang cukup tinggi, dimana yang dianalisa karakteristik hidrodinamika terutama hydrodynamic pressure, volume fraction, dan wave elevation. Simulasi dilakukan pada kondisi calm water. Kinerja hidrodinamika lambung dianalisis secara sistematis pada berbagai variasi Angka Froude, mulai dari Fr 0,4; 0,5; 0,6; 0,7; 0,8; dan 1,2. Simulasi tersebut menguji model bare hull dari NPL, bare hull dengan step, single chine tanpa step, single chine dengan step, multi chine tanpa step, dan multi-chine dengan step. Metode dynamic mesh digunakan pada simulasi ini dan memberikan hasil yang akurat jika dibandingkan dengan simulasi yang menggunakan metode static mesh. Hasil simulasi CFD dibandingkan dengan data uji hasil eksperimen, dimana menunjukkan kesesuaian hasil yang sangat baik. Selanjutnya model dimodifikasi dengan menambahkan chine dan transversed step hull. Hasilnya disajikan dalam kontur hydrodynamic pressure, wave elevation, dan volume fraction. Secara tren, nilai hambatan total meningkat seiring kenaikan froude number. Berdasarkan perbandingan hasil nilai hambatan total dari berbagai model pada Fr 0,8, didapatkan model single chine (SC_OR) memiliki nilai hambatan total terendah. Pada model single-chine dengan step (SC_STEP) memiliki nilai hambatan total tertinggi dikarenakan model konfigurasi tersebut belum secara optimal menurunkan hambatan. Pada kondisi planing di Fr 1,2, didapatkan model “4B_OR” memiliki nilai hambatan terendah dan model “MC_STEP” memiliki nilai hambatan tertinggi.

This study investigates the advantageous configuration of chine and transversed step hull compared to conventional models, using Computational Fluid Dynamics (CFD) method which has quite high accuracy, where the hydrodynamic characteristics are analyzed, especially hydrodynamic pressure, volume fraction, and wave elevation. Simulations are conducted in calm water conditions. The hydrodynamic performance of the hull is systematically analyzed at various Froude Number variations, ranging from Fr 0.4; 0.5; 0.6; 0.7; 0.8; and 1.2. The simulations tested the bare hull model of NPL, bare hull with step, single chine without step, single chine with step, multi-chine without step, and multi-chine with step. The dynamic mesh method is used in this simulation and provides accurate results when compared to simulations using the static mesh method. The CFD simulation results are compared with experimental test data, which shows very good agreement of the results. Next, the model is modified by adding chine and transversed step hull. The results are presented in the contours of hydrodynamic pressure, wave elevation, and volume fraction. In a trend, the total resistance value increases with the increase in the Froude number. Based on the comparison of the total resistance values of various models at Fr 0.8, the single chine model (SC_OR) was found to have the lowest total resistance value. The single-chine model with steps (SC_STEP) had the highest total resistance value because the configuration model had not optimally reduced resistance. In the planing condition at Fr 1.2, the “4B_OR” model had the lowest resistance value and the “MC_STEP” model had the highest resistance value.
