摘要：
In this paper, a resistance performance test on a semi-submersible unmanned ship was carried out under multi-deep navigation conditions, and the hull resistance was numerically simulated by CFD software STAR-CCM+. Then the results of resistance performance test and numerical simulation under surface navigation condition, edge diving navigation condition and fully-submerged navigation conditions were analyzed and discussed. It is concluded that the total resistance under surface navigation condition was relatively low in low speed. And in high speed, the resistance increases rapidly with the increase of speed under the edge diving navigation condition, and the resistance gradually decreases with the increase of the diving depth under fully-submerged navigation conditions. Through visual processing, an analysis of the wave making of the hull under multiple conditions, the surface pressure of the hull, and the flow field near the hull was made. The methods and conclusions of this study provide technical guidance and support for engineering application of semi-submersible unmanned vehicles. © 2022, Editorial Board of Journal of Ship Mechanics.
