Abstract

Fixed-pitch propellers (FPP) are still used on most ships, especially those with minimal
manoeuvring requirements. FPP characteristics have different performance characteristics
between types. Propeller performance during ship maneuver transitions has received little
systematic attention. There are at least four types of propeller operation: Ahead, Crashback,
Backing, and Crashahead. The purpose of this final project is to determine the performance of FPP
propeller type B5-88 with four conditions of operations by using Computational Fluid Dynamics
(CFD). The propeller geometry is made with the CAESES application which provides very
accurate input for the 3D model parameters. The model was created and then a verification and
validation process were carried out using CFD with an experimental model. After obtaining a valid
grid, the model is simulated in 4-quadrant including Ahead, Crashback, Backing, and Crashahead
conditions. The simulation produces thrust and moment data on the propeller which are then
calculated to obtain kT, kQ, and propeller efficiency data. The data comparison from CFD
simulation results with experiments can be shown in a 4-quadrant diagram. The simulation results
show that the error rate in the kT data between the CFD and experimental models is an average of
10%. The Ahead condition has the lowest error rate of 3%. Meanwhile, Crashback and Crashahead
conditions have an error rate of 13%. The error tends to get lower with the value of J approaching
zero in every four propeller operating conditions.
