Numerical Simulation of Pollutant Transport and Diffusion

Finite-difference study of a 1D and 2D advection-diffusion problem, including consistency, stability, CFL condition, convergence and comparison with analytical solutions.

Project Notes

  • Identified from E:/AAAA/projet simulation/simulation.docx and simulation.pdf.
  • The work validates a numerical scheme in 1D, then extends the implementation to 2D transport.
  • Available figures include initial condition, advection-diffusion field, error curve, convergence in space and convergence in time.
