In this study, the general transport equation was subjected to discretization by using the central difference, upwind, hybrid, power-law, exponential scheme and QUICK scheme methods and then solved by using a program prepared in Delphi programming software. In the solution, three different grid systems of 80x100, 160x200 and 320x400 from nodal points were used. The numerical results obtained for Peclet number values of -2, 0, 2, 10 and 20 we presented graphically. The obtained results indicate that hybrid and power-law yield better results as compared to the other discretization methods. The GCI analysis was also provided that 160 x 200 grid system is suitable for such a solution.
