CFD-based numerical simulation of resistance and propeller open water performance of container ship

Abstract

This paper analyses the resistance characteristics and propeller open water performance of the 108 TEU inland container ship using computational fluid dynamics ( CFD ). A numerical simulation pool was constructed based on STAR - CCM+, employing a fixed condition and variable parameter approach to simulate and analyse the ship's resistance and propeller performance at various speeds. The CFD technique facilitates the adjustment of both ship speed and inlet speed coefficient, allowing for the calculation of total resistance and the propeller thrust coefficient. Based on the simulation results, a conversion table outlining the actual ship's resistance and the propeller's open-water characteristic curve is established. The findings indicate that the CFD method effectively simulates the ship's drag characteristics and propeller open-water performance, providing valuable insights for evaluating drag and propeller performance in similar vessels.
