1. AnÃlise de sensibilidade do modelo fluidodinÃmico de um Riser atravÃs do formalismo diferencial perturbativo / Sensitivity analysis for a fluid-dynamic model of a riser via the differential pertubation method
In an oil refinery, the crude oil is pre-heated in order to promote the cracking of the large hydrocarbon chains, transforming the heavy oil into lighter components. These lighter and vaporized oil (gas oil) is now submitted to a fluid catalyst cracking inside a long column denominated riser, where an ascending mixture of gas oil and solid catalyst are simul

2. Estudo experimental e de simulação da fluidodinâmica de um leito de jorro com tubo Draft
The spouted bed has been used in several processes as drying, granulation, catalytic polymerization, residues treatment and materials coating. This application is due to the excellent fluid-particle contact and to the characteristics of the solids circulation. In spite of its extensive application, the spouted bed has some scale-up limitations, so its necess

4. Fluid dynamic modelling and simulation of circulating fluidized bed reactors: importance of the interface turbulence transfer
The main objective of this work is to analyze the importance of the gas-solid interface transfer of the kinetic energy of the turbulent motion on the accuracy of prediction of the fluid dynamic of Circulating Fluidized Bed (CFB) reactors. CFB reactors are used in a variety of industrial applications related to combustion, incineration and catalytic cracking.

5. Simulação orientada a objeto do transporte pneumatico
Particle transportation by a gas stream, commonly named as pneumatic conveying, has been ftequently used in a large variety of industrial processes. This is due not only to the diversity of materiais produced and handled in a granulated form, as also to the great number of possible applications of that operation, which includes since the simple displacement
