摘要

鉴于最近野火的增加，更好地了解它们的动态是至关重要的。为此，平流-扩散-反应模式被广泛应用于野火动力学研究。在这项研究中，我们通过一个额外的平流项引入了以前未考虑的地形影响。此外，我们提出了燃烧函数的线性项，并将其与常用的阿伦尼乌斯定律进行比较，为进一步分析提供了一个更简单的模型。我们对模型动力学的研究结果得到了数值模拟的支持，显示了模型扩展和近似的差异。

Impact of topography and combustion functions on fire front propagation in an advection-diffusion-reaction model for wildfires

Given the recent increase in wildfires, developing a better understanding of their dynamics is crucial. For this purpose, the advection-diffusion-reaction model has been widely used to study wildfire dynamics. In this study, we introduce the previously unconsidered influence of topography through an additional advective term. Furthermore, we propose a linear term for the combustion function, comparing it with the commonly used Arrhenius law to offer a simpler model for further analysis. Our findings on the model’s dynamics are supported by numerical simulations showing the differences of model extensions and approximations.
