Research of Resistance Performance of An Expedition Ship

The resistance performance of expedition ship is researched by the method of model test and numerical simulation in this paper. Then the resistance situation of expedition ship is determined. Compare the resistance result of model test with the resistance result of numerical simulation, and analyze their disparity, then the reason about the disparity is investigated. The flow field and the resistance result of model test and numerical simulation are compared and analyzed. Then the accuracy of the resistance test is verified and the reliability of the method of numerical simulation in this paper is investigated through the mode of mutual authentication. The method of numerical simulation is reliability by verification. So, this method can provide some reference about resistance performance for the ship type development, and it can also provide some basis for verifying the accuracy of the ship resistance test.
