摘要
通过数值模拟和船模试验方法对一型非对称船型不同航向的阻力性能进行分析,计算其不同斜向航行偏角下的阻力,以获得阻力系数随斜向航行偏角变化的关系。计算结果显示,斜向航行角度大于30°时,船体迎流段对黏压阻力的影响将超过去流段,为今后该类船舶的设计提供参考。
The resistance performance of a type of asymmetric hull is studied by numerical simulation and ship model experiment, and the resistance at different oblique navigational deflection is calculated to obtain the relationship between the resistance coefficient and the oblique navigation deflections. The result shows that the entrance has more influence on the viscous pressure resistance compared with the run when the oblique navigational deflection is greater than 30°, providing reference for the design of the kind of ship in the future.
