DETERMINATION OF THE CHARACTERISTICS OF MASS TRANSFER IN CERTAIN COMBUSTIBLE FOREST MATERIALS
A. M. Grishin and A. N. Golovanov UDC 533.6.011 The main characteristics of moisture transfer (the coefficients of moisture capacity and moisture conductivity) for the most widespread elements of combustible forest materials (CFMs), namely, needles of pine, cedar, and spruce, are found experimentally according to the procedure of A. V. Luikov, which is based on the introduction of a scale of moisture-transfer potential. The data obtained are compared with the results of other authors. Analysis of the structure of the CFM elements made it possible to establish that complex processes (desorption, adsorption, and osmosis) associated with a change in the fine structure of the needles during their drying occur inside the CFM elements.
