Název v původním jazyce

Influence of uncertainty in diffusion coefficients on moisture field during wood drying

Popis výsledku v původním jazyce

The paper presents an experimental measurement of diffusion coefficients of wood and theoretical analysis (stochastic analysis) based on influence of uncertainty in these coefficients on moisture field during wood drying simulations. Experimental measurement was used to verify of analytic equations for calculation of diffusion coefficients, which were implemented in the numerical simulations. Histograms show on normal distribution, but stochastic analysis was used for uniform distribution as well. Meanvalue of diffusion coefficient in tangential direction was calculated as 1.016x10^-10 m^2.s^-1 and standard deviation as 0.153x10^-10 m^2.s^-1. Stochastic analysis is based on the Monte Carlo method. The analysis proves that final moisture field has a same probability distribution as the diffusion coefficient (normal or uniform distribution) and also depicts a character of course and distribution of uncertainty in lumber during drying
