Based on Design Constants
Choosing the right propeller involves considering specific design constants tailored to the task at hand. Leveraging Modelica’s a-causal modeling, the Wageningen B-Series polynomials can be solved alongside the design boundaries. This process yields an open-water efficiency curve, dependent on the P/D ratio and the corresponding propeller diameter.
Based on Optimization Algorithms
A more comprehensive propeller optimization can be achieved by integrating speed-dependent hull resistance, the complete propulsion system, and an operational profile. This approach involves employing an optimization algorithm to identify a propeller design that minimizes fuel consumption while meeting the specified operational profile requirements.
