摘要

本文借助格林函数得到了具有不动区域的扩散型管式反应器模型的非稳态解

其中流动区域及不动区域的初始浓度是任意的

进料浓度也是随时间变化的任意函数.首先定义自共轭算子及格林函数

然后用格林函数表示非稳态解

最后求出格林函数的表达式

从而得到所求的解.

Abstract

A general unsteady state solution is obtained by means of Greens function for a dispersion-type tubular reactor with a non-flow zone. Arbitrary initial concentration profiles along the reactor for the flow zone and the non -flow zone are allowed and the feed concentration is time-varying. Firstly a self-adjoint operator is defined and the Greens function is constructed

then the unsteady state solution is found from the Greens function.
