摘要
船舶的拖拽特性有着非常重要的影响,决定了船舶的行驶阻力、动力与操纵性能等,研究舰船的拖拽特性具有重要的意义。本文针对舰船动力系统的螺旋桨进行流体动力学建模,对CFD计算流体力学的原理进行了介绍,并基于计算流体力学CFD对舰船的拖拽特性进行仿真分析。
The towing characteristics of ships have a very important influence,which determines the resistance,power and maneuverability of ships.It is of great significance to study the towing characteristics of ships.In this paper,the hydrodynamic model of propeller in ship power system is established,and the principle of CFD computational fluid dynamics(CFD)is introduced.Based on CFD,the dragging characteristics of ship are simulated and analyzed.
