木材干燥理论架构及其数学表达的研究简报
A Brief Report on Theoretic Framework of Wood Drying and Its Mathematical Expression
摘要
Abstract
Laws of coupled heat and mass transfer,which is about the quantitative relations between flux (i.e.heat flux,moisture flux,osmosis flux)taking place during the process of drying of wood and its driving forces(i.e.temperature gradient,humidity gradient,pressure gradient),were derived by means of physic-me-chanics.At the same time,the general time-dependent partial differential equations on the fields of the temper-ature and the humidity in wood medium were developed from the above transfer laws with the help of some physical laws and mathematic methods.Then,a complete and rigorous set of new system of wood drying theory was composed of coupled heat and mass transfer laws and differential equations in the field of the temperature and the humidity.It provides a theoretical basis of scientific analysis for formulating and regulating technologi-cal parameters of wood drying or heat-treatment.关键词
