Agreement between the numerical results of reduced velocity around an open-water propeller and the measurements is satisfactory.
敞水螺旋桨的脉动速度计算结果与试验结果吻合良好。
This avoids the use of a traditional propeller shaft and puts the propellers in a clear flow of water, which greatly improves efficiency.
这样就避免了使用传统的螺旋轴，将螺旋桨置于干净的水流中，从而大大提高了效率。
