摘要

在一般壁面传热边界条件下,建立了非等温反应器的数值模型。层流和塞流都考虑了。作为调查的一部分,在不同条件下对平衡方程中出现的无量纲群进行了一系列模拟。据观察,这些基团的影响取决于反应器内的热传递程度以及所发生的环境。具体来说,确定了三种不同的传热机制。这些状态本身是内部和外部热传递驱动力的函数。

The effect of heat transfer rate on the characteristics and operation of a tubular reactor

A numerical model of a non-isothermal reactor was investigated subject to a general wall heat transfer boundary condition. Both laminar and plug flow were considered. As part of the investigation, a series of simulations were performed under different conditions with respect to the dimensionless groups appearing in the balance equations. It was observed that the influence of these groups was dependent on the degree of heat transfer within the reactor and with the environment that was occurring. Specifically, three distinct heat transfer regimes were identified. These regimes were themselves functions of the internal and external heat transfer driving forces.
