CSTR中三变量连续放热化学反应模型的非线性分析

研究了修正的CSTR中具有两步连续放热反应的三变量化学模型的非线性动力学现象．建立了CSTR中具有两步连续放热反应的三变量化学模型的量纲一的数学模型．并进行了数值模拟分析．结果表明，本文所研究的化学模型，通过改变对热反馈的控制，可以得到丰富的非线性化学动力学现象，牛顿冷却时间τN和量纲一的活化能量ε对反应的进行具有一定的控制作用．当其它的参数和ε值确定时，在一定的范围内变化τN的值，可以使化学反应产生振荡和混沌现象．

The Non-linear Analysis of the Chemical Reaction Models of Three-variable Consecutive Exothermal Reactions in CSTR

This paper is concerned with the non-linear kinetic phenomenon of thethree-variable chemical models with two consecutive exothermal reactions in CSTR Thenon-dimensional mathematic model of the chemical model is established and analyzedqualitatively by numerical simulation. It is seen from the results of the numericalsimulation that the rich non-linear kinetic phemomenon can be obtained by changingthermal feedback, and the reactions are controlled by the change of the Newton coolingtime τN and non-dimensional active energy ε. Chemical oscillations and chemical chaoscan be obtained by changing τN in a certain sphere under the condition thatthe εand other parameters are determined.
