Two numerical techniques have been developed and compared for solving the three-dimensional advectiondiffusion
equation with constant coefficients. These techniques are based on the finite difference methods
(FDM). By changing the values of temporal and spatial weighted parameters, solutions are obtained for explicit
techniques such as FTCS, FTBSCS schemes. Numerical solution is given for a special case which has been dealt
with in the literature and for which an analytical solution has been provided. Comparison of the results has
confirmed that the FTBSCS numerical approach matches successfully with the analytical solution while the
other technique result in some levels of discrepancy.
