Pengaruh Penambahan Becker Mewis Duct pada Perfoma Propeller B-series

Abstract

Pollution due to sea transportation is a problem that requires consistent handling.
Recent years of research in the field of shipping have focused on reducing exhaust emissions by
increasing fuel efficiency and decarbonization. Decarbonization in the shipping industry can be
achieved by using energy saving devices to reduce fuel consumption. The Energy Saving Device
commonly used in the shipping world is the Becker-Mewis duct (BMD). This study used a
variation of the NACA profile on the Becker-Mewis duct fin. The CFD (Computational Fluid
Dynamics) method is used to analyze the thrust coefficient and torque coefficient. Becker-Mewis
duct was added to increase thrust and torque values. From the results of the analysis that has
been carried out without variations from NACA, the thrust coefficient is 0.1526, the torque
coefficient is 0.0162 and the efficiency is 0.5261. With the NACA 4412 variation, it has a thrust
coefficient of 0.2579, a torque coefficient of 0.0252 and an efficiency of 0.5728. The NACA 4415
variation has a thrust coefficient of 0.2663, a torque coefficient of 0.0260 and an efficiency of
0.5743. With increased efficiency, the addition of Becker-Mewis duct can increase the
performance of the propeller
