This may be used as a base for the calculation of effective wake.
这一性质可以作为计算船体实效伴流的基础。
The effective wake is one of the primary reasons of propeller cavitation and induced ship hull vibration.
实效伴流的不均匀性是引起螺旋桨空泡、振动的主要原因之一。
To avoid the inaccuracy caused by this potential flow assumption, propeller designers have introduced the notion of the effective wake.
为了避免由于势流假设引起的不准确性，螺旋桨设计者引入了实效伴流的概念。
So the effective wake is the properly correction to the propeller analysis method based on potential flow theory which includes the interaction between the propeller and the inflow.
所以，实效伴流是对基于势流理论的螺旋桨分析方法的修正，它包含了螺旋桨和来流之间的相互影响。
