波浪阻力计算取决于海水质点的速度,而速度计算又依赖于所采用的波浪理论。
The results indicate that the wave drag forces calculated by linear wave theory are larger than those calculated by the third order Stokes wave theory for given waves.
作为一个船舶技师,科克雷尔在寻找解决波浪阻力的方法,因为波浪阻力浪费掉了船在水面行驶的大量动力,从而限制了船的速度。
As a shipbuilder, Cockerell was trying to find a solution to the problem of the wave resistance which wastes a good deal of a surface ship's power and limits its speed.
提出了袋形排在静水和波浪中运行阻力的计算新方法。
A new calculation method is put forward of the running resistance of the round-boom type raft in smooth water as well as in waves.
对于波浪中的阻力增加的研究,一直是理论研究和工程应用的重点。
On the researches of added resistance in waves, the added resistance prediction based on the strip approach is usually used.
后来气垫船跨越英吉利海峡,平衡地在波浪上方行驶,波浪不再产生阻力。
Later it crossed the Channel, riding smoothly over the waves, which presented no problem.
这说明波浪增阻影响函数可以作为高速船舶最小阻力船型设计与改进的基本依据。文中还讨论了增阻影响函数的性征与变化规律。
It is pointed out that the influence function of added resistance in waves can be used for the design and modification of ship form of high speed ship with least resistance.
通常将垂直柱体在波浪场中的受力分为正向力(顺流力)与升力,它们是由干粘性流绕钝体产生的摩擦阻力和由于水流绕柱分离产生涡漩而形成柱表面压力分布的不均匀变化而造成的。
When waves act on a vertical cylinder, there are in-line and lift forces. They are caused by the viscous effect, which induces the surface frictional force and flow separation and vortex shedding.
