Stability of boiling shock

Аннотация

This paper studies the stability of boiling shock formed when limiting (near spinodal) superheatliquid superheat is reached in a flow. In these conditions the boiling shock is always accompanied by oscillations specific to problems of this class. Physical analysis of the mechanism of the generation of such oscillations is performed and estimates of pulsations for the reactive force of the outflowing medium are found which are in good agreement with the experiment. A conclusion is made that the mechanism of jet disintegration observed in these conditions may serve as an efficient method for liquid fuel jets atomizing in a number of technical applications.
