Investigation of Flow in Pipe Bends. Design of a Special Water Separator.

In wet-steam pipes, a state of equilibrium is established between coalescence, suspended droplet breakup, liquid splash against the pipe walls, wave generation and spray in the fluid wall-layer. Author describes an experimental study of the aerodynamic flow configuration in a pipe circuit containing elbows and the observed tendency of these to collect water on their generatrixes in the plane of symmetry, and suggests a suitable water-trap design for such cases.
