15 and RTSM. Fluent 6.2 was used to solve the Navier-Stokes equation and gambit as mesh generator. The major problem of the marine propeller study is the cavitation effect, where in conventional modeling, such as the momentum theory and the blade element theory, this effect was ignored (Wald, 2006). However, Young and Shen (2007) showed that there is some change in the performance of the propeller due to the cavitation effect. Therefore, the modeling of propeller must consider this effect to ensure that the performance of the propeller can be predicted accurately. CFD can significantly predict the thrust and torque of the propeller under the influence of cavitation. Mishima and Kinnas (1996) showed the predicted value of thrust and torque in cavitating and non-cavitating values by using Reynolds-averaged Navier–Stokes (RANS) simulation, agreed with experiment values. Two geometry domains were created in this study, which were for steady and unsteady simulations respectively. For the steady simulation, the domain geometry was the same as that of Rhee and Joshi (2003) where only one blade was simulated. But for the unsteady domain, a complete propeller was simulated with an infinite cylinder in the middle of the blade to serve as a hub. Two types of propeller were investigated in this study, which were the MP017 and Sien Maru propellers. For both cases, the turbulent model (k omega) was used to model the turbulent flow. The solver was segregated, the pressure velocity coupling was SIMPLE and the descretezation method was QUICK scheme. To solve the problem FLUENT 6.2 was used.

Design and Analysis of Marine Propeller with Leading Edge Protuberances

Abstract: The humpback whale is extremely manoeuvrable despite its size. This study investigates the effects of biologically inspired leading-edge protuberances (tubercles) of humpback whale flipper on INSEAN E779a marine propeller. The study of humpback whales and their flipper performance was the impetus to modify the leading edge of a marine propeller in order to gain a hydrodynamic advantage. This study examines the preliminary design and analysis for the effect of the leading-edge modification on propeller performance at various advance co-efficient. Simulations were executed on propeller with leading- edge sinusoidal protuberances, in order to compare the performance characteristics with that of a propeller with a smooth leading edge. The propeller is designed using CREO Parametric 3.0 and the open water test is simulated using Moving Reference Frame (MRF) approach for complete propeller geometry using ANSYS Fluent 16.2.

Design & Analysis of a surface propeller using FEM

Design & Analysis of a surface propeller using FEM

Abstract— Propeller design aims at achieving high propulsive efficiency at low levels of vibration and noise, usually with minimum cavitation. Achieving this aim is difficult with conventional propellers, as ships have become larger and faster propeller diameters have remained limited by draught and other factors. Surface piercing propeller offers an attractive alternative to high-speed crafts, which operate under limited draught. The performance of the vehicle depends upon the efficiency of the propeller. The geometric shape and its surface finish will decide the efficiency of the propeller. The material used is carbon UD and aluminium. The present research basically deals with the modeling and Analysis of the propeller using composite material of a marine vehicle having low draft. A propeller is complex 3D model geometry. CATIA modeling software is used for generating the blade model and tool path on the computer. Sectional data, pitch angle of the propeller are the inputs for the development of propeller model. Finite element analysis was carried out using ABAQUS. The propeller model developed in CATIA is converted in to IGES file and then imported to HYPERMESH for developing fine mesh of the model. As a part of the analysis static structural testing was conducted by varying material properties in pre-processing stage.

Underwater Technology Research Group (UTeRG), Center for Robotics and Industrial Automation (CERIA), Fakulti Kejuruteraan Elektrik, Universiti Teknikal Malaysia Melaka, 76100 Durian Tunggal, Melaka, Malaysia. *[E-mail: shahrieel@utem.edu.my] In the underwater world, an autonomous underwater vehicle (AUV) is created to assist in underwater research. This project presents a design analysis and modelling of AUV using computer aided design (CAD) simulation software, SolidWorks. The scope of this project divided into two parts: (a) AUV design and (b) analysis of battery enclosure stress and strain simulation and flow simulation of 3-blade propeller T100 thrusters. The AUV was designed part by part first and then the assembly of all the parts is carried out. In the simulation stress and fluids were applied on the enclosure box and a thruster, respectively, to observe the reaction of the parts as the frame and pressure hull from Blue ROV design. The result of the stress simulation shows that the enclosure box is very durable and can withstand up to 718.10 Pascal equivalents to 73.2 meter underwater depth. Furthermore, the outcome of flow simulation by using SolidWorks has shown that the maximum velocity of thruster flow is 4.939 m/s, while the acceleration of 5.655 m/s 2 of the AUV is calculated by using thrust force and mass of the AUV.

the aerofoil stalls, the accuracy of the performance predictions and hence the propeller performance predictions would become questionable. No Mach effects could be modelled in the wind tunnel. Despite the limitations mentioned above, the minimum induced loss design methodology of Larrabee (1979a) was capable of producing a feasible propeller design for the chosen HALE UAV application. The method produced a propeller capable of flying the mission and the analysis method used to predict the performance at operational points far removed from the design point was able to produce acceptable results at the lower thrust coefficients (lower disc loadings) and lower advance ratios experienced during the climb phase, see Figure 7.13. It was difficult to assess the ability of the method to predict the required power coefficients due to the influence of the wind tunnel on the measured results.

M.R. Khoshravan and A. Paykani [21] studied the design method and a vibration analysis of a carbon/epoxy composite drive shaft. Effects of different parameters such as critical speed, static torque, fiber orientation and adhesive joints were studied. The fibers orientation angle has a big effect on the natural frequency of the drive shaft. The fibers must be oriented at zero degree to increase the natural frequency by increasing the modulus of elasticity in the longitudinal direction of the shaft. A mass comparison between steel and composite drive shafts has been done. The substitution of composite shaft has resulted in considerable weight reduction about 72% compared to conventional steel shaft.

Hydrodynamic Design Structural Analysis and Optimization of Marine Propeller Blade

Hydrodynamic Design Structural Analysis and Optimization of Marine Propeller Blade

Today, conventional marine propellers remain the standard propulsion mechanism for surface ships and underwater vehicles. In general, the propeller is that component of the ship which converts the engine power into the driving force of the ship. The modifications of basic propeller geometries into water jet propulsors and alternate style thrusters on underwater vehicles have not significantly changed to determine and analyse propeller performance. However, the propellers are required to generate adequate thrust to propel a vessel at some design speed ensuring some “reasonable” propulsive efficiency. Considerations are made to match the engine’s power and shaft speed, as well as the size of the vessel and the ship’s operating speed, with an appropriately designed propeller. The above conditions specified are interdependent, and knowledge on desired operating speed for a given vessel is required, however, the complexity of the flow field in which the propeller must operate efficiently will lead a designer to layout a propeller to overcome most of the dilemma. Another difficulty which arises during propeller action is the variation of inflow, which has a great influence on propellers. Hence, the range of design is restricted for designers.
