Convective transport of combustion products in the atmosphere above large fires. (English. Russian original) Zbl 0729.76078

Fluid Dyn. 25, No. 4, 532-537 (1990); translation from Izv. Akad. Nauk SSSR, Mekh. Zhidk. Gaza 1990, No. 4, 47-52 (1990).
Summary: A nonstationary axisymmetric model of the development of a turbulent convective combustion product column above a fire in a stratified atmosphere is proposed. The model takes into account the compressibility of the gas and the diffusion of the aerosol particles and makes it possible to predict the dynamics of ascent of the convective column, the height of the cloud and the distribution of the aerosol in the atmosphere. The numerical and experimental data are compared.
