“…Han et al [18] used Star-CCM+ and Abaqus coupling approach to study the marine composite propellers; the results were reasonably close to experimental outputs. Paik et al [19] investigated different composite propellers numerically and experimentally. In 2020, Shayanpoor et al [20] performed an analysis by considering the CFD-FEM-based approach under the two-way coupling method on the KP458 propeller.…”

This paper aims to assess a new fluid–structure interaction (FSI) coupling approach for the vp1304 propeller to predict pressure and stress distributions with a low-cost and high-precision approach with the ability of repeatability for the number of different structural sets involved, other materials, or layup methods. An outline of the present coupling approach is based on an open-access software (OpenFOAM) as a fluid solver, and Abaqus used to evaluate and predict the blade’s deformation and strength in dry condition mode, which means the added mass effects due to propeller blades vibration is neglected. Wherein the imposed pressures on the blade surfaces are extracted for all time-steps. Then, these pressures are transferred to the structural solver as a load condition. Although this coupling approach was verified formerly (wedge impact), for the case in-hand, a further verification case, open water test, was performed to evaluate the hydrodynamic part of the solution with an e = 7.5% average error. A key factor for the current coupling approach is the rotational rate interrelated between two solution domains, which should be carefully applied in each time-step. Finally, the propeller strength assessment was performed by considering the blades’ stress and strain for different load conditions.

“…The bend-twist deformation can function as an immediate pitch adjustment which mitigates the periodic load variations [1,2,[6][7][8][9][10][11]. Other researchers have designed and manufactured FRP propeller blades with passive adaptive bend twist deformation [4,5,[9][10][11][12]. For more information about periodic load variation on propeller blades and the mechanics of how a pitch adjustment physically mitigate load variations, refer to [1, 7,[9][10][11].…”

“…In recent years, there has been an increased focus on the optimisation of composite propellers from both structural and marine engineers points of view. Several different design concepts for twisting propeller blades have been looked into [1, [4][5][6][9][10][11][12][13][14]. In addition, hydrodynamic performance and modelling methods to establish hydrodynamic performance are being mapped [14][15][16][17][18][19][20][21].…”

Experimental Verification of the Elastic Response in a Numeric Model of a Composite Propeller Blade with Bend Twist Deformation

Adaptive composite propeller blades showing bend twist behaviour have received increasing interest from hydrodynamic and structural engineers. When exposed to periodic loading conditions, such propellers can be designed to have higher energy efficiency and emit less noise and vibration than conventional propellers. This work describes a method to produce an adaptive composite propeller blade and how a point load experiment can verify the predicted elastic response in the blade. A 600 mm-long hollow full-size blade was built and statically tested in the laboratory. Finite element modelling predicted a pitch angle change under operational load variable loads of 0.55°, a geometric change that notably compensates for the load cases. In the laboratory experiment, the blade was loaded at two points with increasing magnitude. The elastic response was measured with digital image correlation and strain gauges. Model predictions and experimental measurements showed the same deformation patterns, and the twist angle agreed within 0.01 degrees, demonstrating that such propellers can be successfully built and modelled by finite element analysis.

“…The advantages of hull optimization and related devices optimization (such as propellers and hydrofoils) have been demonstrated by several authors. Many design optimization approaches have been used in the design of traditional propellers [1,2], unconventional propulsion systems [3,4], appendages [5], and the optimization of the entire hull shape [6,7]. Recently, a lot of development has been done on the design of unconventional vessels with special mission profiles, from the standard mono-hull shapes [8,9], to unconventional multi-hulls [10,11], or hulls with special shapes, such as the Small Waterplane Area Twin Hull or SWAT [12].…”

Shape optimization is a very time-consuming and expensive task, especially if experimental tests need to be performed. To overcome the challenges of geometry optimization, the industry is increasingly relying on numerical simulations. These kinds of problems typically involve the interaction of three main applications: a solid modeler, a multi-physics solver, and an optimizer. In this manuscript, we present a shape optimization work-flow entirely based on open-source tools; it is fault tolerant and software agnostic, allows for asynchronous simulations, and has a high degree of automation. To demonstrate the usability and flexibility of the proposed methodology, we tested it in a practical case related to the naval industry, where we aimed at optimizing the shape of a bulbous bow in order to minimize the hydrodynamic resistance. As design variables, we considered the protrusion and immersion of the bulbous bow, and we used surrogate-based optimization. From the results presented, a non-negligible resistance reduction is obtainable using the proposed work-flow and optimization strategy.
