摘要: 对有限长圆柱状催化剂内发生强放热反应时的多态特性,本文提出了较为完整的研究方法,包括:(1)将有限北方法与非线性连续性算法及奇性理论结合,开发了有限元全区域分析方法,作为研究非线性偏微分方程多解的基本工具;(2)在高数值效率因子计算中,改进传统方法,开发了高效、准确的新方法,通过实验数据检验了有限元全区域分析方法的可靠性,结果令人满意。

Abstract: An integrated method has heen suggested aiming at the investigation of multiple states of effectiveness factor for cylindrical catalyst pellet. It includes; (1) Finite - Element Global Analysis, which is the combination of Finite -Element Method with Continuation Method and singularity theory, is used as a basic tool to deal with the multiple solutions of partial differential equation. (2) a new numerical method for large -value effectiveness factors, which overcomes the shortcomings of traditional methods and owns features of efficiency and accuracy, has been developed. Finite -Element Global Analysis is tested by experiment data and the agreement is satisfactory.
