Abstract:
The mathematical model of the two-phase turbulent jet allowing to count and single-phase jets is given. With use of this model calculations of single-phase and two-phase jets with step unevenness of parameters in their initial sections (double-circuit coaxial jets) — the gas and two-phase jets which are in the external gas jet are carried out. The carried-out calculations showed that identical change of the ratio between initial diameters and initial speeds of internal and external jets exerts various impact on change of parameters on length of coaxial double-circuit gas and two-phase jets. The received results testify to the possibility of change of two-phase jets range due to the choice of the ratio between diameters of internal and external jets and ratios of speeds in their initial sections.
