A stability analysis is presented for staggered schemes for the governing equations of compressible flow. The
method is based on Fourier analysis. The approximate nature of pressure-correction solution methods is taken into
account. 2001 IMACS. Published by Elsevier Science B.V. All rights reserved
Matlab script for solution to the driven cavity problem on a staggered grid using a divergence formulation and second-order Runge-Kutta time integration.
This program incorporates the FV method for solving the Navier-Stokes equations using 2D, Cartesian grids and the staggered arrangement of variables. Variables are stored as 2D arrays. SIMPLE method is used for pressure calculation. UDS and CDS are implemented for the discretization of convective terms, CDS is used for the diffusive terms. The boundary conditions are set for the lid-driven cavity flow. Only steady flows are considered.
The 2D CFD Program NaSt2D
The program is a 2D solver for the incompressible, transient Navier-Stokes equations including the temperature equation and free boundary problems. It uses finite differences for discretization on a structured equidistant staggered grid, central and upwind (donor-cell) discretization of the convective parts and an explicit time stepping scheme. The free boundary value problems are treated with the MAC technique.
