Suppression of thermal expansion and flaming combustion of condensed substances at different heights of the beginning of motion of the water array

Results of an experimental study of heat and mass transfer and phase transitions during suppression of thermal expansion and flaming combustion of condensed matter (CM) by an example of typical combustible materials in the forest (mixtures of leaves, conifer needles, and twigs) by means of the action of a non-atomized water array at different stages of its transformations are reported. The liquid volume and the height of its discarding with respect to the CM surface are varied with allowance for the known stages of water array transformations to illustrate possible differences in the cross-sectional areas of these arrays, which determine the water-CM contact area. The characteristics of CM burning termination are obtained as functions of the height of the beginning of water array motion.
