Abstract

The universality of the pseudo wet bulb temperature has been established in the drying of macroporous inerts, microporous inerts, and microporous swellable materials using water and methyl alcohol as the liquids. The pseudo wet bulb temperature is a new constant temperature intermediate between the wet bulb and dry bulb temperatures of the air during the second falling rate period. This temperature is calculated from consideration of the heat transfer to, and vapor diffusion from, liquid evaporating at the liquid-air boundary. The experimental results agree with that calculated from the equation proposed by Nissan, Bolles and George.

물 및 Methyl Alcohol 과 같은 液體에 젖은 巨大孔 不活性 微少孔 不活性 및 微小孔 濕潤性 物質을 乾燥할때 假濕球 溫度가 普扁的으로 形成되며 假濕球 溫度는 空氣乾操의 第 2 減速期中 乾球溫度와 濕球溫道間에 나타난 하나의 새로운 一定溫道이다. 이 溫度는 液體 空氣 境界에서의 熱傳達, 蒸氣壙散, 液體蒸發 現象을 考慮한 式으로 計算되며 Nissan Bolles 및 George가 誘導한 式에 依하여 計算된 數値는 實險結果値와 一致한다.
