Studying wildfire fronts using advection-diffusion-reaction models

K Mitra, Q Peng, C Reisch - arXiv preprint arXiv:2401.17468, 2024 - arxiv.org
In this work, we study the propagation of wildfires using an advection--diffusion--reaction
model which also includes convective and radiative heat loss. An existing model is …

Robust and structure-preserving time-discretisation and linearisation schemes for singular and degenerate evolution systems arising in models for biofilm growth

RKH Smeets, K Mitra, IS Pop, S Sonner - arXiv preprint arXiv:2404.00391, 2024 - arxiv.org
We propose and analyse numerical schemes for a system of quasilinear, degenerate
evolution equations modelling biofilm growth as well as other processes such as flow …

Existence-Uniqueness Theory and Small-Data Decay for a Reaction-Diffusion Model of Wildfire Spread

AG Morgan - arXiv preprint arXiv:2406.00575, 2024 - arxiv.org
I examine some analytical properties of a nonlinear reaction-diffusion system that has been
used to model the propagation of a wildfire. I establish global-in-time existence and …
