Acesso em:.https://repositorio.ufpa.br/handle/2011/7700The Generalized Integral Transform Technique is applied solve the Navier-Stokes equations for an irregular geometry duct in sinusoidal shape in an incomprehensible and laminar flow. The formulation was used in terms of current function. A general filter has been adopted that adapts to the irregular contour to increase the convergence of the solution. Different geometries were analyzed by modifying the length ratio (λ/a) and the height ratio (Hmin/Hmax) for Reynolds number in the range 25-400. For the same Reynolds number rising one of the two geometrical parameters the flow recirculation is lower and the decrease of the parameters increases the flow recirculation. The recirculation for λ/a = 16 and Hmin/Hmax = 0.7 is low in Reynolds = 400. Considering the configuration where λ/a = 4 and Hmin/Hmax = 0.3 the flow recirculation is observed at low Reynolds numbers (Re = 25). The friction factor, based on the viscous forces, calculated showed the same pattern of the literature.Acesso AbertoTransformadas integraisEquações de Navier-StokesMecânica dos fluídosTécnica da Transformada Integral Generalizada (GITT)DissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA MECANICA::FENOMENOS DE TRANSPORTE::MECANICA DOS FLUIDOS
