摘要：

Using dye visualization techniques, we have observed vortex structures within the jet region of round transverse jets which, to the best of our knowledge, have not been reported before. These structures confirm the existence of a pair of negative bifurcation lines in the surface flow of the pipe and the conjecture of Abramovich (1963) concerning additional vortical motions within the jet itself.
