Abstract:
The transom immersion on the ship can influence the ship resistance.
Therefore, it is important to investigate on the amount of drag that contributed
from different transom immersion. For this research, all the design is a NPL
mono-hull ship. The hull was selected from the MAX SURF library. The
collected data were used as benchmark for validation purposed and
comparison with the result that researcher obtained from Computational Fluid
Dynamic (CFD).This project will use Computational Fluid Dynamic (CFD)
software to simulate the resistance or drag of the ship. This project will use the
FLOW TECH SHIP FLOW 6.03 for the study. The simulation in this research
was done using CFD (SHIP FLOW). In SHIP FLOW, the configuration was set
up using COURSE, WTRAN and FSFLOW. The configuration was conducted
using this setting. The result was obtained when the computational simulation
has completed. The obtained result was tabulated and a graph was plotted to
perform Grid Independence Study (GIS). This study analyzed of different
transom immersion ratio AT/AX at 0.5, 0.7, 0.8 and 1.0. The model or the hull
form chosen for this study is the NPL Round bilge archived from MAX SURF
library. The Computational Aided Design (CAD) Rhinoceros 5 was used for
the re-design transom area. At the end of project, the best transom immersion
ratio was at 0.5 because it produces the lowest total resistance. The highest
total resistance was produced by transom immersion 1.0. The total resistance
increases as the transom immersion increases. The total coefficient increases
as the transom immersion ratio increases. The higher the transom immersion,
the higher the wave making made by the model.
