Numerical Investigation of Physicochemical Processes Occurring During Water Evaporation in the Surface Layer Pores of a Forest Combustible Material

“…The conditions of suppression (termination) of the thermal decomposition reaction of typical FCMs with their surface layers exposed to water (especially to fi nite-size droplets and fi lms) have inadequately been studied to date. The reason is that the mechanism underlying the suppression of reaction can change substantially when water passes into the FCM pores or spreads over its surface (as deduced from the analysis of the results of numerous investigations, for example [6][7][8], of heat and mass transfer processes occurring in moist wood and FCM). It is of interest to carry out a numerical analysis of the processes of heat transfer, phase transformations, and of chemical reaction (response) on suppression of the FCM thermal decomposition reaction and under different heat transfer conditions at the water-FCM interface (especially during the passage of water with a temperature of T >T d into the FCM pores).…”
