Alternating Direction Implicit Formulation of the Cosine-based DQM for Solving Navier-Stokes Equation


In this article, we have discussed a new application of alternating direction implicit formulation of the differential quadrature method (ADI-DQM) (Al-Saif A.S.J. et al. 2011,2012) (1, 2) on Navier-Stokes equations . the weighting coefficient computing by Cosine expansion based. Numerical results of one example, show that the present method has been high accuracy ,good convergence comparing with using weighting coefficients is Lagrange interpolation polynomial.
