On FTCS Approach for Box Model of Three-Dimension Advection-Diffusion Equation

الملخص EN

This paper describes a numerical solution for mathematical model of the transport equation in a simple rectangular box domain.

The model of street tunnel pollution distribution using two-dimension advection and three-dimension diffusion is solved numerically.

Because of the nature of the problem, the model is extended to become three-dimension advection and three-dimension diffusion to study the sea-sand mining pollution distribution.

This model with various advection and diffusion parameters and the boundaries conditions is also solved numerically using a finite difference (FTCS) method.
