Abstract

As a part of the important thing in ship design is propeller design. Propeller its self has many kinds of the design. This study investigates the effect on the performance of ducted propeller. The investigation was carried out by solving the Navier-Stokes equations with the Computational Fluid Dynamics (CFD) method. These simulations were compared in accordance SHUSKIN nozzle that has 3 types of design. Each type of thruster model indicates different force and torque. Thus, for the analysis will be generated by each model and it can be discovered that which model has the most optimal for the thrust. The analysis by using CFD indicates the change of fluid flow around the ducted propeller. The results showed that the nozzle on the propeller will give the extra of thrust for the performance of propeller.

Highlights

Many remote operated vehicle (ROV) have been developed for the maintenance and inspection of ocean structures
The nozzle is important to use in propeller as ROV thruster
Reynold Averaged Navier-Stokes equations (RANS) have been developed based in the concept that a velocity and length scale are sufficient to described the effect of turbulence in flow

Summary

Introduction

Many remote operated vehicle (ROV) have been developed for the maintenance and inspection of ocean structures. Most of them in practical use are self-propulsive with umbilical cable. A self-propulsive ROV can be guided to target more accurately than towed one. A tethered self-propulsive which is usually used to inspect and maintain ocean structures [1]. Propeller design is to obtain the optimum propeller which applies to minimum power requirements and against maximum efficiency conditions at an adequate revolution number. Two methods are used in the propeller design. The first is use diagrams obtained from the open water propeller experiments for systematic propeller series. Form from the previous research, the nozzle produces a decrease in the propulsive efficiency. The nozzle is important to use in propeller as ROV thruster
