Numerical solution of 2-d advection-diffusion equation with variable coefficient using du-fort frankel method

The advection-diffusion equation or transport equation is investigated further. A simple numerical approximation such as Du-Fort Frankel methods for advection-diffusion equation with variable coefficient is employed. The obtained results are compared with its analytical solution in a simple unit square domain. The method and results are then being used to solve advection-diffusion in the real-world problems for the more complicate irregular domain.
