本文对无限大空间和圆柱形空间中的中、小螺距螺旋涡丝的自诱导速度表达式进行了推导。这一结果补充了已知的无限空间中大螺距螺旋线的开尔文公式。
A derivation of an expression for the self-induced velocity of a helical vortex filament with moderate and small pitch is presented for the cases of an infinite space as well as a space bounded by a cylindrical tube. This result supplements the known Kelvin’s formula for helix with large pitch in an infinite space.
