Numerical simulation of the self-propelled performance of container ships based on CFD

In order to analyse the self-propelled performance of 98TEU inland container ships, this paper adopts the CFD method to numerically simulate the self-propelled performance of the ship based on STAR-CCM+. This paper adopts the method of fixed speed and variable rotation speed, by adjusting the rotation speed so that the thrust generated by the propeller can overcome the resistance. CFD technology is used to simulate the ship drag, propeller thrust and other parameters generated when the ship sails on its own, and based on the simulation results, a real-vessel speed prediction curve is established to obtain the ship's target speed under the power of the main engine. The research results show that the CFD method can accurately simulate the self-sailing of the ship, and the method provides a reference for the self-sailing performance evaluation of similar ships.
