Threedimensional finitevolume method for incompressible flows with complex boundaries
Abstract
A finitevolume method is presented for calculating incompressible 3D flows with curved irregular boundaries. The method employs structured nonorthogonal grids, cellcentered variable arrangement, and Cartesian velocity components. A special interpolation procedure for evaluating the mass fluxes at the cellfaces is used to avoid the nonphysical oscillation of flow variables usually encountered with the cellcentered arrangement. The SIMPLE algorithm is used to handle the pressurevelocity coupling. A recently proposed low diffusive and bounded scheme is introduced to approximate the convection terms in the transport equations. The computer code and the relevant data structure are so organized that most of the code except the implicit linear solver used is fully vectorizable so as to exploit the potential of modern vector computers. The capabilities of the numerical procedure are demonstrated by application to a few internal and external threedimensional laminar flows. In all cases the CPUtime on a grid with typically 28,000 grid nodes was below half a minute.
