Abstract
Hydrodynamic effects are severely affecting the performance of a Marine Propeller. Basically, manuvering of an Unmanned Aquatic Vehicle's is controlled by its propeller, which is drastically depends on the fluid. Therefore the study about fluid behaviour and its effects are mandatory to enhance the efficiency of the marine propeller. In this work deals, the hydrodynamic force estimations on the marine propeller by using both theoretical formulae and numerical analysis. The aim of this work is to obtain the fine tuned hydrodynamic forces of marine propeller for its performance enhancement. Fundamentally, complexities involved in the force estimation approaches are represent the fluid behaviour and environmental conditions. Standard formulae are used for estimations of hydrodynamic forces. CATIA is used for the generation of conceptual design on the marine propeller. ANSYS Fluent 16.2 is used for numerical simulation, in which fluid is provided the ocean water properties. Finally, the hydrodynamic forces are compared for future work.
