Influence of droplet distribution in a “water slug” on the temperature and concentration of combustion products in its wake

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

A numerical study has been made of the influence of the droplet distribution in a “water slug” on the integral characteristics of heat and mass transfer (temperature and concentration of the gases in its wake) in motion through high-temperature combustion products of typical combustible wood. Limiting values of the parameters characterizing the position of the droplets relative to the neighboring droplets in the “water slug” at which minimum temperatures and concentrations of the combustion products in its wake are attained under the conditions of the greatest possible completeness of water evaporation, have been established. It has been shown that a series–parallel droplet distribution in the “water slug” is expedient for efficient action on the high-temperature gases.
