Shaping of a free jet of overheated water at different distances from a cylindrical channel

This paper presents an experimental investigation of the dependence of the shape, structure, and opening angle of a water jet on the degree of superheating. The relationship between different boiling modes and characteristic shapes of a boiling jet has been revealed. It has been found that the shape and the opening angle of a superheated liquid jet under the same thermodynamic conditions change in different ways depending on the length of the jet. The changes in the opening angle of a boiling jet are presented in the meter, decimeter, and centimeter ranges.
