RESUMO

In this investigation a control volume-finite element method (CVFEM) using a ninenoded finite element with quadratic interpolation functions has been developed for numerical simulation of incompressible, viscous, transient fluid flows. The Navier-Stokes equations in primitive varibles U,V,pare used as the mathematical model. The mass weighted interpolation (MAW) is also implemented for the convective terms of the equations, into the element considered. The obtained results for some test problems agree quite good with results of other numerical methods and/or experimental results.
