1. Comparison between Neutron Diffraction measurements and numerical simulation of residual stresses of a Wire-Drawing process
In this work, a drawing processed was simulated to calculate forces and the resulting residual stresses in the material. The calculated residual stresses were compared with experimentally measured residual stresses by the Neutron Diffraction Method. The modeled process was the Wire Drawing. The necessary parameters to model the process were taken from an ind

2. Estudo do fenômeno de Clogging na região da válvula tampão por meio da dinâmica dos fluidos computacional
The clogging phenomenon is a yet to be solved problem and there is little knowledge about the fluid-dynamic relation to inclusions deposition. The purpose of this study is to help to understand the inclusions deposition mechanism, employing a CFD model to describe the steel flow in a stopper rod. A 3D geometry of the nozzle region was built and the results w

3. Efeitos térmicos e fluido-dinâmicos devidos a um agitador eletromagnético para tarugos
O uso de agitadores eletromagnéticos (EMS) durante o lingotamento contínuo tornou-se imprescindível para a obtenção de aços de melhor qualidade. Embora os efeitos da agitação durante o processo de solidificação sejam pouco conhecidos do ponto de vista teórico, pode-se estudar esses efeitos sobre o perfil de escoamento antes do aço solidificar. Es

4. Numerical simulation CFD in the quenching process / Simulação numerica CFD no processo de tempera
In the quenching heat treatment is a great difficulty to understand the different cooling profiles occurring at the surface and subsurface of the material, that define the structure formed and the final properties desired. The formation of different types of structures in the material can occurs due to uneven cooling caused by fluid dynamic conditions of the

5. Estudo experimental e numerico da dinamica de movimento de Riser em catenaria com escoamento interno / Experimental and numerical study of the motion dynamics of catenary riser considering internal flow
The pipe which transports fluids from the petroleum production well, on the seabed, up to the production unity, on the sea surface, is named riser. The main objective of this work is to characterize the dynamic response of a riser, hanging in catenary configuration, with the influence of the internal flow of hydrocarbons. It was observed from literature, tha

6. Influencia das taxas direcionais de resfriamento na evolução da solidificação em sistemas metal/molde
The microstructure and properties of castings depend on cooling conditions during solidification,or more precisely, on cooling rates and consequently on the thermal resistance of metal/mould and mould/environment interfaces. The main objective of this work consists on analysing the solidification process by using mathematical tools, and on the characterisati
