| dc.description.abstract | У цій статті представлена та вивчається нова комбінована модель, яка поєднує біологічний та механічний аспекти, що описують відповідно процес виробництва біогазу та стисливий двофазний потік біогаз–фільтрат під час анаеробного біорозкладу органічних речовин на сміттєзвалищі, що розглядається як реактивне пористе середовище. Отримана модель описується реакційно-дифузійною системою бактеріальної активності у поєднанні зі стисливою двофазною системою потоку неоднорідного пористого середовища. Здійснено аналіз та чисельну апроксимацію моделі у межах варіаційного підходу. Запропоновано повну дискретну систему, засновану на часовій схемі BDF другого порядку та P1-сумісному скінченному елементі, та отримано ефективний алгоритм для спряженої системи. Виконано чисельне моделювання для 2D та 3D прикладів відповідно до теоретичного аналізу. | |
| dc.description.abstract | In this article, we present and study a new coupled model combining the biological and the mechanical aspects describing respectively the process of the biogas production and the compressible two-phase leachate-biogas flow during the anaerobic biodegradation of organic matters in a landfill, which is considered a reactive porous medium. The model obtained is governed by a reaction-diffusion system for the bacterial activity coupled with a compressible two-phase flow system of a non-homogeneous porous medium. We carry out the analysis and the numerical approximation of the model within a variational framework. We propose a full discrete system based on a second-order BDF-time scheme and P1-conforming finite element and we derive an efficient algorithm for the coupled system. We perform some numerical simulations in 2D and 3D examples in agreement with the theoretical analysis. | |
