The flowfield around the turbine is calculated using the prescribed wake model. In particular, a vortex core model and a vorticity dissipation model are introduced to cope with the divergence generally existing in vortex wake methods.
风力机的绕流用预定涡尾迹模型确定,并引入涡核模型和考虑粘性引起的耗散效应对模型进行修正,解决了涡尾迹方法在大叶尖速比时普遍存在的计算发散问题。

This is caused principally by the vortex core of whirling water in the draft tube.
这种振动主要是由尾水管中的旋涡带所致。
The tangential velocity distribution measured in this study is similar to a vortex core existing along the jet axis.
旋转射流的切向速度分布相当于射流中存在一个旋转的涡核。
The result showed that the stream function of vortex tube was expressed as the superposition of the stream functions of vortex filament within the vortex core.
结果显示：涡管流函数是时间的周期函数，并被表征为一系列在涡核内均匀分布螺旋涡丝流函数的叠加。
