Query: On the Efficiency of the Iterative Techniques for Solving Incompressible
  Navier-Stokes Equations   It is well known that the choice of the iterative method is crucial in
determining the speed of the converged solution. This article presents a
detailed comparison between several iterative techniques for solving
incmopressible Navier-Stokes equations. The numerical approaches implemented in
the solver include Jacobi, Gauss-Siedel, Successive Over Relaxation,
Alternating Direct Implicit and Multigrid methods. The results reveal that
multigrid method is the most powerful iterative method among all other methods
investigated in terms of the computational time and the number of iterations.
