Torricelli's curtain: Morphology of laminar jets under gravity

M. Rabaud, N. Ribe

While the form of a fluid jet issuing horizontally from an orifice was first studied by Torricelli (1643), this classic problem in fluid mechanics still holds surprises. When a laminar jet issues from the end of a pipe, it divides into primary and secondary jets with a thin vertical curtain of fluid connecting them. We are currently using laboratory experiments and numerical simulations to study this unexpected behavior.
