本文研究了无限长直涡丝在刚性球逼近下的演化。流体被认为是无粘性和不可压缩的。当球体离涡足够远时，涡丝的形状用线性理论近似确定。随后的演变是通过积分的非线性运动方程数值。
The evolution of an infinitely long straight vortex filament in the presence of an approaching rigid sphere is considered. The fluid is regarded as being inviscid and incompressible. The shape of the vortex filament when the sphere is sufficiently far away from the vortex is determined approximately using linear theory. The subsequent evolution is followed numerically by integrating the nonlinear equation of motion.
