可压缩流场中对流反应扩散方程的研究

Study of an Advection-Reaction-Diffusion equation in a compressible flow field

Federico Bianco, Sergio Chibbaro, Roger Prud'homme

摘要:

本文通过数值求解对流反应扩散方程,研究了一维燃烧情况下的波前传播。简化了物理模型,使得不考虑耦合现象,反应流体是气体的二元混合物。给出了可压缩流场的解析解。我们分析了可压缩燃烧和生物问题的基础研究中使用的流行模型之间的差异。然后,我们研究了压缩性对不同反应类型的前界面动力学的影响,并讨论了反应在完成前停止的条件。

英文摘要:

We have studied the front propagation in a one dimensional case of combustion by solving numerically an advection-reaction-diffusion equation. The physical model is simplified so that no coupling phenomena are considered and the reacting fluid is a binary mixture of gases. The compressible flow field is given analytically. We analyse the differences between popular models used in fundamental studies of compressible combustion and biological problems. Then, we investigate the effects of compressibility on the front interface dynamics for different reaction types and we characterise the conditions for which the reaction stops before its completion.
