Abstract

ABSTRACT: A spreadsheet for the numerical simulation of one-dimensional unsteady-state nonisothermal moisture diffusion in solid wood in the transverse direction below the fiber saturation point was developed in this work. Calculations for solving a pair of partial differential equations describing the moisture diffusion based on a finite-difference method were performed. Experimental validations revealed that the spreadsheet provides predictions of moisture diffusion in wood as accurately as a commercial simulation software package does. This spreadsheet simulation can help people involved in manufacturing, utilizing, or researching wood products to implement a simple and convenient numerical simulation of moisture diffusion in wood without any special skill and any specific software.
