摘要
精准评定木材的导热系数对木材干燥、热处理等工艺优化及模型构建意义重大。近年国内外学者主要通过实验法与模拟法两方面解析木材的导热行为。本文在综括木材导热系数的实验法与模拟法的基本原理、特点及应用研究现状基础上,从检测方法的规范性、模型构建的合理性两方面,分析不同检测方法的科学性、精确性及实用性,旨在为木材导热系数的精确测算提供借鉴与参考。
Accurately evaluating the thermal conductivity of wood plays a significant role for optimizing wood processes,such as wood drying and heat treatment and constructing simulation models.Recently,domestic and foreign scholars have mainly focused on analyzing the thermal conductivity behavior of wood through experimental and simulation methods.This paper summarizes the basic principles,characteristics,and applied research status of experimental and simulation methods for the thermal conductivity of wood.In terms of the standardization of testing methods and the rationality of model construction,the scientificity,accuracy,and practicality of different testing methods are analyzed.The goal is to provide guidance and reference for achieving the precise measurement of the thermal conductivity of wood.
