摘要

在某些情况下,振荡模式下的反应对目标产物具有更高的选择性。为了组织这种模式下的生产,有必要确定发生波动的条件,并考虑波动的本质。在这项工作中,我们对无自催化的振荡反应的基本动力学模型进行了参数分析。找到了系统振荡时的参数边界。构建了系统的相位图和分岔曲线。分析了系统的静止状态。确定了静止状态的类型和数量。结果表明,在某些参数下,系统有三种静止状态:两个不稳定节点和一个鞍点。通过对基本模型进行参数分析,可以为计算更复杂的实际反应模型选择初始近似值。

Parametric Analysis of a Mathematical Model of a Catalytic Oscillator

Parametric Analysis of a Mathematical Model of a Catalytic Oscillator

In some cases, a reaction in the oscillatory mode has a higher selectivity for the target product. To organize production in this mode, it is necessary to determine the conditions under which fluctuations occur, as well as to consider the very nature of the fluctuations. In this work, a parametric analysis of the basic kinetic model of an oscillatory reaction without autocatalysis was made. The boundaries of the parameters at which the system oscillates were found. Phase portraits of the system and bifurcation curves were constructed. Stationary states of the system were analyzed. The type and number of stationary states were identified. It was shown that the system at certain parameters has three stationary states: two unstable nodes and a saddle. Parametric analysis of basic models will allow selecting initial approximations for calculations of more complex models of real reactions.
