Optimal Selection of Marine Propellers Based on Wageningen B-Series

Abstract:

In the scope of this research, we shall examine the feasibility of applying an optimization method to ship propeller selection. The idea is to model the “traditional” selection process as a constrained optimization problem. Throughout this particular paper, an objective function (propeller performance) is optimized, subjects to a number of constraints imposed by cavitation, required propeller thrust, and available engine power. In the beginning, we select Wageningen’s B-series propellers as our study object because of its fidelity in experimental data, and, for the sake of simplicity, we shall use Sequential Quadratic Programming (SQP) method to solve the optimization problem. By introducing this new approach, we want to exploit the power of numerical machine to deal with a computational challenge; selecting a propeller not only best fits the design requirements but also in a most effective manner. Moreover, this method could be further developed, and be applied to the optimization of ship design.
