S15  Métodos Híbridos em Engenharia Mecânica    Titulo: LAMINAR FORCED CONVECTION THROUGH RECTANGULAR DUCTS WITH UNIFORM AXIAL AND PERIPHERAL HEAT FLUX   Resumo : ABSTRACT. HYDRODYNAMICALLY DEVELOPED, THERMALLY DEVELOPING LAMINAR FLOW OF A NEWTONIAN FLUID INSIDE STRAIGHT RECTANGULAR DUCTS WITH BOUNDARY UNIFORM AXIAL AND PERIPHERAL HEAT FLUX IS ANALYTICALLY STUDIED USING THE GENERALIZED INTEGRAL TRANSFORM TECHNIQUE. LAMINAR FLUID FLOW, CONSTANT FLUID PROPERTIES, HIGH PÉCLET NUMBER AND NEGLIGIBLE VISCOUS DISSIPATION HYPOTHESIS ARE EMPLOYED. THE ENERGY EQUATION FOR THE UNKNOWN TEMPERATURE DISTRIBUTION IS TRANSFORMED BY THE USE OF THE INTEGRAL TRANSFORM TECHNIQUE RESULTING IN A COUPLED SYSTEM OF FIRST ORDER ORDINARY DIFFERENTIAL EQUATIONS FOR THE UNKNOWN TRANSFORMED TEMPERATURE PROFILE. SUCH SYSTEM IS SOLVED AND THE TEMPERATURE PROFILE CAN BE RETRIEVED BY USING THE INVERSION FORMULA. NUMERICAL RESULTS ARE PRESENTED FOR QUANTITIES OF PRACTICAL INTEREST WITHIN THE THERMAL ENTRY AND THE FULLY DEVELOPED REGION, FOR A WIDE RANGE OF THE AXIAL DISTANCE AND SEVERAL ASPECT RATIOS. SOME OF THOSE THERMAL QUANTITIES ARE: BULK FLUID TEMPERATURE, AVERAGE WALL TEMPERATURE, AVERAGE AND LOCAL NUSSELT NUMBERS. KEYWORDS: FORCED CONVECTION, RECTANGULAR DUCT, GENERALIZED INTEGRAL TRANSFORM TECHNIQUE.     Autores : Aparecido, João Batista Lindquist, Cláudio 0     Trabalho Completo :   COBEM99 | Comissão  Organizadora | Palestras | Sessões Técnicas | Autor | Simpósios e Sessões Especiais | Revisores |  Título  dos  Trabalhos | Local
