Abstract

Penambahan bentuk buritan menjadi bentuk Stern flaps dan Stern wedge akan berpengaruh terhadap nilai hambatan dan pola aliran yang terjadi di bagian buritan sehingga hambatan yang terjadi akan lebih kecil. Fokus dari penelitian ini adalah nilai pengurangan hambatan kapal yang dihasilkan ketika kapal beroperasi dengan stern flaps atau stern wedge. Simulasi dilakukan dengan metode Computational Fluid Dynamics (CFD) menggunakan software NUMECA Fine Marine. Hasil analisa tersebut dapat diketahui perbedaan nilai hambatan pada kapal akibat penambahan bentuk buritan dan pola aliran yang terjadi. Berdasarkan hasil simulasi yang dilakukan, kinerja bentuk stern yang paling optimal mengurangi hambatan adalah bentuk Stern flap 1%Lpp dengan sudut 4⁰. Nilai hambatan berkurang hingga 9,33 kN atau sebesar 3,5% pada kecepatan 28 knot. ================================================================= The addition of stern design to establish Stern flaps and Stern wedge that will be affect the value of resistance and flow patterns sistem that follow in the stern so that the resistance will be reduce. The focus of this reseach is reduction in ship resistance generated when the ship operates with stern flaps or stern wedges. The simulation is done by Computational Fluid Dynamics (CFD) method using NUMECA Fine Marine software. The results of the analysis can be seen in the addition of the stern and flow patterns sistem that follow. Based on the result of simulation, the most optimal stern form performance reduces the resistance is Stern flap 1% Lpp with angle 4⁰. The resistance value is reduced to 9.33 kN or 3.5% at speed 28 knots.
