Abstract
In the previous report, a transient method to determine the moisture diffusion coefficient for material is described. A mathematical model in the method is deribed by using some assumptions, and measuring errors are caused by the assumptions. The errors are analyzed by means of Laplace transformation method. In this paper, analyzed errors are examined by simulations for several materials. It is shown that errors, caused by heat and moisture interaction in the simulation, are 30% larger than analyzed errors. Therefore, analysis method is improved for more accurate prediction of the errors. Moreover, the improved error analysis is applied to compensate errors. It appears to be of significant value in the determinaton of the moisture diffusion coefficient.
