25. Bicos dispersores da industria do petroleo : analise bidimensional aplicando a fluido dinamica computacional
The atomizers of a petrochemical fluid catalytic cracking unit (FCC) have a main role of atomizing the gas-oil at the base of the catalytic reactor (riser). Until the beginning of the decade of 1990 the atomizers used in the units of PETROBRAS suffered pronounced erosion, that causes deficiencies which affects adversely the whole process yield. The conventio

26. Numerical simulation of a rocket motor with chemical reaction flow / Simulação numérica do escoamento em um motor foguete com reação química
This work presents a numerical simulation of the flow field in a propellant rocket engine chamber and exit nozzle using techniques to allow the results to be taken as starting points for designing those propulsive systems. This was done using a finite volume method simulating the different flow regimes which usually take place in those systems. As the flow f

27. Metodologia de obtenção de resultados em fluido-dinamica computacional : aplicação a reatores tanques agitados
In this thesis, procedure for obtaintion of vector and scalar fields is shown and applied to stirred tank reactors. The methodology of the present work is emphasized through case studies with a Newtonian fluid, water, and a non-Newtonian system, polystyrene. Both fluids are contained inside a stirred tank reactor. The system stirred tank reactors is studied
