Pengaruh Pemasangan Double Triangular Vortex Generator Posisi Sejajar Terhadap Tahanan Kapal

Abstract

Ship resistance is one of the problems in ship planning. The shape of the hull is designed with the slightest possible resistance. Along with the rapid development of science and technology, the design of fast boats has undergone many changes to obtain a design that can reduce the ship's resistance. One way is by adding a vortex generator on hull modifications using double triangular shapes. The research was carried out with variations in speed and trim. The data processing method in this research uses numerical methods for modelling vortex generators and conducting a resistance analysis. The results show the difference in resistance between the ship model without a vortex generator and the ship model using a vortex generator. Then, the results are compared according to speed and trim. Comparison of resistance values using ship models vortex generator ranging from 5,68% to 15,01% less than the resistance of the ship model without using vortex generator. The most significant reduction in the value of resistance is at FnV 2,816.
