Aqueous solutions of isopropylalcohol with various compositions were used for the experiments. The drying process was examined in detail by measurement of the drying rate, the material temperature and the distribution of moisture content. The drying rate and the material temperature vary even for the period of surface evaporation. It was found that the drying rate and the material temperature are influenced by the composition of solution at the surface. Moreover, the reverse phenomena of moisture content gradient was observed for some initial composition. Even for such conditions, the capillary suction pressure monotonically increases towards the surface., 2 成分溶液を含む砂層の乾燥における物質移動機構が実験的に研究された。様々な初期組成のIPA水溶液が実験に用いられた。2 種類の試料容器を用いて乾燥速度,材料温度,及び含水率分布を測定することにより,乾燥過程の詳細な考察がなされた。乾燥速度, 材料温度は一定値を示さないことや含水率勾配の逆転現象が観察された。混合溶液の乾燥速度と材料温度は初期組成に依存し,材料内部における溶液の移動は毛管吸引力によって引き起こされることがわかった。, Article, 富山大学工学部紀要 47, 115-123.(1996)}, pages = {115--123}, title = {2成分溶液を含む砂層の乾燥機構}, volume = {47}, year = {1996} }
