Research Progress on Experimental and Simulation Methods for Thermal Conductivity of Wood
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.
