A new second-order time-accurate fractional-step method for solving unsteady incompressible Navier-Stokes equations on hybrid unstructured grids is presented. The nonstaggered grid method, originally developed by Chow (1983, AIAA J. 21, 1525) for steady flow and further extended by Zang et al. (199
We present new finite difference schemes for the incompressible Navier-Stokes equations. The schemes are based on two spatial differencing methods; one is fourth-order-accurate and the other is sixth-order accurate. The temporal differencing is based on backward differencing formulae. The schemes us
