AbstractAbstract
[en] To study the laminar fully developed flow close to a circunferencial square hump placed at the wall of a smooth circular pipe is studied. An experimental set up was used to determine the reattachment legth and the velocity and shear stress profiles of the flow for different Reynolds numbers. Simple relations were obtained from the analysis of the data for the reattachment length, maximum velocity and maximum shear stress in different positions along the flow and different Reynolds numbers.

Estudam-se as caracteristicas do escoamento interior em regime laminar, plenamente desenvolvido junto a um obstaculo anular de seccao longitudinal quadrada. Por meio de uma bancada de testes sao medidos os comprimentos de separacao a jusante do obstaculo e as pressoes differenciais locais para varios numeros de Reynolds, em diferentes seccoes, com a finalidade de determinar os perfis de velocidade e de tensao de cizalhamento. Analisam-se comportamentos dos comprimentos de separacao e das velocidades e tensoes maximas ao longo do escoamento. (Autor)Original Title
