Alternating Direction Implicit Formulation of the Differential Quadrature Method for Solving the Unsteady State Two-Dimensional Convection-Diffusion Equation

In this paper, we propose alternating direction implicit formulation of the differential quadrature method (ADI-DQM) for calculating the numerical solutions of the two-dimensional unsteady state convection-diffusion equation with appropriate initial and boundary conditions. The results confirm that this method has a high accuracy, good convergence and less workload compared with the other numerical methods.
