Numerical research of heat and mass transfer processes in water vapors and gaseous thermal decomposition products mixture above the combustible wood on the conditions of chemical reaction termination in it

The numerical analysis has been made of complex interrelated heat and mass transfer processes, chemical reactions and phase transformations under the thermal decomposition reaction suppression of typical combustible wood (needles of a pine, fir, fir-tree and larch, branches of a pine, fir, birch and larch, cones of a pine, leaves of aspen) by the “water slug” trace. Characteristic times have been calculated of the thermal decomposition reaction suppression of typical combustible wood at typical temperatures in “water slug” trace and the thickness of warmed material layers.
