Summary
A novel scheme for viscous incompressible flows on unstructured grids is introduced. A staggered positioning of the variables is used: the pressure is located in the centroids of the triangles while the normal velocity components are placed at the midpoints of the faces of the triangles. The pressure-correction approach is employed to deal with the divergence-freedom constraint of the velocity. Spatial discretization is discussed. For the lid-driven cavity problem, good results are obtained.
