Abstract:
Objectives This paper is intended to study the viscous flow field around a ship under oblique conditions and provide a research basis for ship maneuverability.
Methods Using commercial software STRA-CCM+, the SST k-ω turbulence model is selected to predict the hydrodynamic performance of the KVLCC2 model at different drift angles, and predict the hull flow field. The pressure distribution of the ship model at different drift angles is observed and the vortex shedding of the ship's hull and constraint streamlines on the hull's surface are also observed.
Results The results show that numerical simulation can satisfy the demands of engineering application in the prediction of the lateral force, yaw moment and hull surface pressure distribution of a ship.
Conclusions The research results of this paper can provide valuable references for the study of the flow separation phenomenon under oblique conditions.
