停留时间分布 流体质点通过装置时,其停留时间长短的分布情况。有些质点迅速流出,有些质点则可能在装置内滞留较长时间。流体在反应器内滞留将会严重影响反应的最终结果。 描述流体停留时间分布的函数 包括停留时间分布密度函数、累计停留时间分布函数、年龄分布函数。 ①停留时间分布密度函数(或称停留时间分布函数)记为E(t),因而又称E(t)函数。对一稳定流动系统,在某一瞬间进入(或流出)装置的物料量Q中,停留时间在t和t+dt之间的物料量dQ所占的分率dQ/Q定义为E(t)dt。图1之a即为一般的E曲线的示意。根据E(t)的定义,停留时间在各个不同时间间隔内的物料所占分率的总和为1,即E(t)满足下面的归一化条件: 。 ②累积停留时间分布函数 记为F(t),因而又称为F(t)函数。指流过系统的物料中,停留时间小于t(即停留时间介于0~t之间)的物料所占的分率。即 或
