【Abstract】 Based on the reliable calculation of numerical value,the powerful function of an illustrating and easily learned language system,Matlab can be used to compute numerical solutions for a dynamic model of heat and moisture transfer with condensation in porous fabric.The action of Matlab with finite-difference and numerical integration for solving the heat and moisture transfer model in textile materials is also described in the paper.The distributions of temperature,moisture concentration and water content in the porous fabric for different materials are numerically computed and compared.The consistency between numerical simulation results and experimental data demonstrates the effectiveness of the proposed numerical algorithm.更多还原
