Abstract:

In order to know the present situation of research on theories of fluids penetrating wood overall and systematically, the paper presents a summary of the main styles and flowing theories of fluids in porous medium, the main penetrating channels of fluids in wood, and the main theories and experimental methods of research on fluids penetrating wood. Several major development directions of research on theories of fluids penetrating wood are also put forward. Advanced technologies are supposed to be adopted to observe dynamically during the whole continually process of liquids penetrating wood in the experimental observation on the research methods aspect, and more rational models of wood simple structure for fluids penetration, especially liquids penetration should also be established for exacting description on penetrating channels with less parameters. The mature theories and methods used in the heat and mass transfer, liquids permeability of construction material such as cement, stone and brick, soil and rock oil underground to establish the planar or three-dimensional theory model which conforms to the practical process of liquids penetrating wood unsteady are predicted in the theoretical studying. The two methods are suggested be combined to describe the mechanism of fluids penetrating wood qualitatively and quantitatively.
