S25  Métodos Numéricos    Titulo: A NEW COMPUTATIONAL ALGORITHM FOR THERMAL-HYDRAULICS ANALYSIS OF INDUSTRIAL PLANTS   Resumo : THIS WORK PRESENTS AN ORIGINAL ALGORITHM USING A NUMERICAL SOLUTION SCHEME OF A PHYSICAL MODEL REPRESENTING THE THERMAL-HYDRAULIC BEHAVIOR OF AN INDUSTRIAL PLANT. THIS MODEL IS DESCRIBED BY ONE DIRECTION EQUATION IN THE PREFERRED FLOW DIRECTION. A HOMOGENEOUS FLUID SLIP MODEL IN THERMAL DYNAMIC EQUILIBRIUM IS ASSURED. THE ALGORITHM PRESENTS A TOTALLY IMPLICIT AND ITERATIVE SCHEME IN TIME, WHEN NO REVERSE FLOW OCCURS. IT IS RECURRENT IN SPACE, PRODUCING A MARCHING ALGORITHM IN SPACE. RESULTS ARE PRESENTED FOR TWO TEST CASES. THE FIRST ONE WAS COMPARED TO RELAP5/MOD3.2 RESULTS. THE SECOND CASE WAS COMPARED TO AN ANALYTICAL SOLUTION. BOTH RESULTS SHOWED LOW ABSOLUTE ERRORS, NO NUMERICAL DIFFUSION AN REAL TIME PROCESSING.     Autores : Alvim, Antonio Carlos Marques Carmo, Eduardo Gomes Lapa, Nelbia da Silva     Trabalho Completo :   COBEM99 | Comissão  Organizadora | Palestras | Sessões Técnicas | Autor | Simpósios e Sessões Especiais | Revisores |  Título  dos  Trabalhos | Local
