Abstract

The results of the research of a hydraulic stream, dispersion of which is carried out by the generation of pulsations of pressure in a stream outflowing from the sprinkler (hydroimpulsive liquid jet) are presented. On the basis of phenomenological analysis of the data of high-speed photography of the liquid jet, we pick out the elementary constituents of process of dispersion including:

- forming the sequence of identical portions of liquid, consisting of high-speed and low-speed liquid jets;

- their non-elastic collision, attended with transformation of the portion in a structure consisting of a drop and remaining area of low-speed stream, which are crushed in the gas stream flowing them around, forming a total torch.

The mathematical model of dispersion taking into account the features of physical picture of process has been developed, the formulae linking dispersion characteristics, form of torch and jet range with frequency and amplitude of the pressure pulsations generated in a stream have been got. The conducted experiments have shown the good coincidence of their results with design data. The results obtained can find wide application for creation of thermal screens, suppression and disinfection of the harmful blowouts, fire extinguishing and so on.
