“…Yusvika et.al., [13] predicted cavitation in marine propellers based on temperature and fluid properties and the results show that the cavitation trend is more aggressive at high water temperatures than at low temperatures. Another study was conducted on a CFD approach to propeller cavitation by Mohammad Danil et al, [14] and Zheng et al, [15], and the CFD approach to the performance of propeller was investigated in the previous research by Arifin et al, [16], and Lovibond et al, [17].…”

Kaplan series propeller has the potential to improve ensuring the high ship propulsion performance of the operation. In this study, a Kaplan propeller is evaluated with a Controllable Pitch Propeller (CPP) behavior such as angle of attack and the number of blades. The propeller blades which are studied are 3, 4, and 5 blades with the angle of attack about 10.3⁰, 15.3⁰, and 20.0⁰. The method in this study is using Computational Fluid Dynamic (CFD) simulations. Moreover, surface pressure, thrust, torque, and efficiency are evaluated due to the influence of the angle of attack variations. It has been found that varying the angle of attack significantly affects the distribution of the pressure surface of the propeller. The pressure gradually increases at the higher level of the angle of attack. Furthermore, it is well known that variations in the angle of attack and the number of blades significantly affect propeller performance as expressed by propeller thrust and torque values. Thrust and efficiency tend to increase at higher levels of the angle of attack. However, it tends to decrease at the propeller with more blades on it
