2. Contribuições ao estudo da fluidodinâmica em leitos de jorro utilizando-se CFD
In the present thesis are discussed two important questions regarding spouted bed fluidynamics: scale-up procedure and semicylindrical vessel for inferring fluidynamic behavior in cylindrical systems. To evaluate these points were applied numerical simulation by CFD techniques and experimental analysis by using data from laboratory and literature. The scale-

3. Experimental and numerical study of spouted bed fluif dynamics
Spouted beds, originally invented in Canada by Mathur and Gishler (1955) as an alternative to fluidized beds for handling coarse particles, are now widely studied in a variety of physical operations, such as drying, coating and granulation. In this work the particle velocity, minimum spouting flow rate and characteristic fluid-dynamic curves of the spouted b

4. 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

6. Hot-melt coating in spouted and fluidized beds: study of the process, particle characterization and tablet pressing. / Revestimento de partículas por solidificação de material fundido em leitos de jorro e fluidizado: estudo do processo, caracterização das partículas e preparo de comprimidos
No revestimento por solidificação de material fundido o agente de revestimento é aplicado em seu estado liquefeito e se solidifica na superfície do substrato, formando a cobertura desejada, eliminando o uso de solventes. O presente trabalho teve como objetivo estudar dois tipos de processo: revestimento de partículas grandes em leito de jorro e revestim

7. Secagem de clara de ovo em leito de jorro fluidizado bidimensional. / Drying of egg white in a 2D spouted fluidized bed.
The objective of this study was to evaluate an egg white drying process using a two-dimensional spouted fluidized bed dryer with glass spheres as the inert particles. A complete 24 factorial design was used, with 3 central and 8 axial points, using the following independent variables: temperature (55-95ºC), total drying air flow rate (97.1-138.3 m3/h), rati

8. Desenvolvimento de equipamento para recobrimento de partículas em leito de jorro fluidizado / Apparatus Developing for Particle Coating in Spoutfluidized bed
The coating of solids particles has the most important application in controlled release technical. Needing to suppress agglomeration is among determination of process conditions that attend requirement to production capsules with characteristics required for protection or controlled release. The purpose of this work is joining the requirements of process th

9. Investigations on drying of oil shale particles / Investigações sobre a secagem de particulas de xisto
Xisto pirobetuminoso é uma rocha sedimentar que contém querogênio, um material orgânico que se encontra disseminado em sua estrutura mineral. O querogênio é extraído por aquecimento a altas temperaturas, em reatores conhecidos como retortas, 1iberando óleo e gás. Este óleo quando refinado produz destilados com as mesmas características encontradas

10. Analise da fluidodinamica de leito de jorro durante o recobrimento de particulas
Among the several unit operations that seek the modification of superficial characteristics of solid partic1es, the spouted bed appears as a substitute for the fluidized bed, to process a great variety of coarse solid materiaIs. The use of this technique for the partic1e coating, initially employed in the pharmaceutical industry, is promising, which motivate
