Numerical Study of Deformation Drops of Water in Gas Stream

Abstract

Mathematical model developed on basis of experimental data about processes of deformation organohydrocarbon drops of fuel in stream of oxidant. Numerical investigation of integral characteristics of deformation of droplet organohydrocarbon fuel with size of drops − 4.5 mm , speed of oxidant − 2 m / s, temperature of 298 K has been completed (in accordance with the conditions of the experiment). Specific change of surface longitudinal and cross section and of organohydrocarbon drops of fuel during its gravity precipitation in time has been shown. It showed satisfactory agreement theoretical and experimental data. The developed model is the basis for solving problem of collapse (crushing) of drops of coal-water and organohydrocarbon slurry during their motion in a gaseous medium at a subsonic speed.
