A conservative finite-volume second-order-accurate projection method on hybrid unstructured grids (Q1284550)

This paper describes a finite volume discretization method to compute steady, two-dimensional incompressible viscous recirculating flows using hybrid unstructured meshes, composed of triangles and quadrilaterals. The method includes a second-order least squares scheme for convection discretization, and a fractional step projection method based on staggered grid arrangement for pressure velocity coupling. Numerical results are reported to demonstrate the robustness, second-order accuracy, and flexibility of the proposed method. \(\copyright\) Academic Press.
