水分を含む壁体の遮熱性の数値解析と公式化

摘要

Most of the building material contains some extent of moisture, for example, about 21% of the mass of gypsum board are water of hydration. Thermal stagnation near a boiling point is observed in the fire resistance test for such walls, and it makes significant contribution to the thermal resistance of the wall. This research treats this effect separately from the thermal resistance by the thermal properties of material itself. Aside from the numerical analysis, the mathematical formula is derived for fire resistance of moisture containing wall.%1次元熱伝導モデルを作成し、実験で観測された現象について数rn値解析による検討を行い、次の2点を明らかにした。rn1.実験で観測される温度停留t_(stg)、微視的にみれば存在せず、熱rn電対自体の大きさや水分移動が影響していると考えられる。
