In our experiment two laminar round jets collide in water forming a zero-momentum toroidal vortex
and this flow is modeled theoretically. First, the linearized time dependent basic solution for the
starting round jet is derived in a straightforward manner. Then a superposition of these solutions is
used to model the frontal collision of two round jets. The resulting flow patterns are calculated and
compared with the experiments. The comparison shows good qualitative agreement. 2003

I. INTRODUCTION
Compact vortex structures in a homogeneous fluid are a
well-known phenomenon. They are easily formed in water,
