多孔質固体内伝熱解析への画像データの特徴抽出の適用

抄録

Much time was required to estimate the effective thermal diffusivity by the calculation with use of the image data. The reduction method of calculation time for the estimation of effective thermal diffusivity has been developed. The thinning method and the characterization of image data are used for the reduction. The calculation time is reduced to 1/230. The effective thermal diffusivity measured using the LASER flash method agrees well with that calculated.
