Computational fluid dynamics (CFD) modelling of a flow field surrounding marine propellers is difficult due to complex geometry and rotational effects. A propeller is a kind of fan that converts rotational motion to thrust to convey power. A difference in pressure is created among the front and back surfaces of an airfoil-shaped blade as well as the fluid accelerates back of the blades, producing two forces: one on the longitudinal direction of the ship, known as the thrust force, and the other, known as the tangential force, that produces the required torque. For the vast majority of parts, maritime propellers are made from aluminium or bronze alloys. In this study, a performance comparison is done between the original and modified blade version. SOLIDWORKS 2016 is used for propeller design, while ANSYS 2019 is used for structural analysis. The primary aim is to increase the rate of thrust force with a modified design and a constant input power. This study also implements cost estimation along with cost-cutting strategies. An effective cost-estimating framework can help you gain a competitive edge.
