摘要：
An experimental study has been made of the dynamics of boiling-up of a jet of superheated water in outflowing through short cylindrical channels of diameters 0.33 and 0.63 mm. The change in the shape of the flashing jet at different degrees of superheating has been tracked. It has been established that upon the transition from the stationary process of outflow to a nonstationary one, the opening of the jet is not full. Stepwise changes in the angle of opening of the jet in explosive-boiling up transition at the temperature Ts = 470 K were found. From the experimental data, the author determined the change in the opening angle of the jet of superheated water as a function of the degree of its superheating.
