Abstract
This paper considers the effect of vortices on liquid outflow from open vessels. One of the simplest possible arrangements is investigated: an axisymmetric vertical cylindrical vessel with an outlet in its base. A simple spiral vortex is either introduced by supplying the liquid tangentially to the vessel and the outlet or suppressed by the installation of a vortex breaker. A new flow regime for well-developed vortex flow is identified. In this flow regime the variation of the liquid level in the vessel with the flowrate is relatively independent of the method of supply of the liquid to the vessel, and can be correlated by a simple equation.
