Interaction of a gas-droplet turbulent jet with a cocurrent high-velocity high-temperature gas flow. (English. Russian original) Zbl 1271.76347

J. Appl. Mech. Tech. Phys. 49, No. 3, 417-424 (2008); translation from Prikl. Mekh. Tekh. Fiz. 49, No. 3, 85-94 (2008).
Summary: A mathematical model and a method for calculating a gas-droplet turbulent jet with allowance for velocity nonequilibrium and virtual mass of the condensed phase during turbulent fluctuations and also heat and mass transfer within the three-temperature scheme are developed. Methodical calculations are performed. The results of these calculations are in reasonable agreement with available experimental data. The structure of the gas-droplet jet in a cocurrent high-velocity high-temperature gas flow is studied by numerical methods. The ratio of intensities of heat and mass transfer between the phases and turbulent diffusion transfers of substances is found to be different at the initial, transitional, and basic segments of the jet. This difference is responsible for the nonmonotonic axial distribution of vapor density and the lines of the halved mass flow of the condensed phase.
