The content explores the well-posedness and asymptotic behavior of the Advection-Diffusion-Reaction (ADR) model. It investigates the existence, uniqueness, and positivity of solutions, employing semigroups and global attractors theories. The analytical solution of a two-dimensional Advection-Diffusion Equation is presented, along with the use of Explicit Finite Difference schemes for simulations. The study delves into Partial Differential Equations (PDEs) and their applications in various scientific fields. Numerical methods for solving ADR equations are discussed, emphasizing the challenges and properties of different schemes. The article also highlights the importance of establishing a global attractor for understanding the long-term behavior of the system.
