Resumo: The aim of this paper is to solve axysssimetric problems found in nuclear reactors engineering. Thus, a stabilized finite element formulation for the solution of the Navier-Stokes and energy equations for axyssimetric problems has been developed and tested. This formulation has been implemented in the NS_SOLVER_MPI_2D_A program developed at the Parallel Computation Laboratory of the Instituto de Engenharia Nuclear (LCP/IEN) and is now available either for safety analysis or design of nuclear systems. The results show the simulation of the mixed convection phenomena that occurs in the downcomer of a PWR nuclear reactor.
