Research on Numerical Simulation of Large Bulk Carrier Speed Prediction
In order to serve the research and development(R&D)of merchant ships and the present goal of low carbon emission,a numerical simulation based on computational fluid dynamics(CFD)are executed to study the resistance and speed characteristics of a 210 000 DWT bulk carrier.The numerical simulation including hull resistance,propeller open water characteristic,and ship self-propulsion.The results of present simulation are fully compared with the model test.The results show that the errors of the resistance,and propulsion efficiency between numerical simulation and experiments are respectively within 1％,and 3％.The accuracies of resistance and speed prediction satisfy the requirement of engineering application.The present numerical simulation on the bulk carrier is available for the support to R&D on bulk carrier and other main ships in the future.
