2. Investigação do escoamento bifásico gás-líquido em uma coluna de bolhas retangular por meio da técnica CFD / Investigation of two-phase gas-liquid flow in a rectangular bubble column using CFD technique
This study aims to evaluate the main forces which act in gas-liquid flow in a rectangular bubble column of dimensions 150cm x 26;4cm x 3;1cm (height (H) x width (W) x depth (D)), with centralized aeration, using CFD technique. The proposed case is based in a experimental study of an air-water system operating in homogeneous bubbly flow, with initial liquid h

3. Simulação do escoamento monofásico em um estágio de uma bomba centrífuga utilizando técnicas de fluidodinâmica computacional
Oil production and exploration techniques have evolved in the last decades in order to increase fluid flows and optimize how the required equipment are used. The base functioning of Electric Submersible Pumping (ESP) lift method is the use of an electric downhole motor to move a centrifugal pump and transport the fluids to the surface. The Electric Submersib

4. Análise da viabilidade técnico -econômico -ambiental da operação do sistema elevatório Tietê -Billings no suprimento de água e eletricidade na Região Metropolitana de São Paulo / Analysis of technical feasibility, economic and environmental operation of the lift system Tietê-Billings in the supply of water and electricity in the metropolitan region of São Paulo
O presente estudo analisa a água da bacia do alto Tietê, tanto como insumo na forma de água potável produzido em oito Estações de Tratamento de Água (ETA), quanto insumo na forma de energia hidráulica, ou ainda, como água residuária gerada por diferentes atividades de origem antrópica. O maior problema desta bacia é a água residuária que é lan

5. AN ANALYSIS OF THE DROP BREAKUP PROCESS IN AN OIL IN WATER EMULSION FLOWING TETWEEN PARALLEL DISKS / ANÁLISE DO PROCESSO DE QUEBRA DE GOTAS DE UMA EMULSÃO ÓLEO-ÁGUA NO ESCOAMENTO ENTRE DISCOS PARALELOS
Oil production is usually associated with the production of water, which may be found as a continuous phase or as a dispersed phase, in emulsions. Emulsions may be found in almost all the production stages: in reservoirs, production wells, production facilities, pipelines, in processing and in storage. The Electric Submersible Pump (ESP) is one of the method

6. Partition of root water extraction between soil layers with distinct hydraulic properties / Partição da extração da água do solo por plantas entre camadas com propriedades hidráulicas distintas
Root water extraction is determined by soil hydraulic conductivity and water potential gradients, both dependent on soil water content. In this dissertation the experimental test of a root water extraction and partition model is described for a plant whose root system is divided over soil layers with distinct hydraulic properties. An experiment was conducted

7. Partição da extração da água do solo por plantas entre camadas com teores de água distintos / Partition of root water extraction between soil layers with distinct water contents
Water shortage is one of the most limiting factors for agricultural production. The understanding of factors that rule the extraction of soil water by plants and its distribution along the root system under contrasting hydraulic conditions is important for fine-tuning hydrological models which are a reference for crop growth models, meteorological models, am

10. Detecção condutométrica sem contato: uma nova ferramenta para monitoramento de interações biomoleculares em microssistemas analíticos / Contactless conductivity detection: a new tool for monitoring biomolecular interactions on analytical microsystems
The study reported in this thesis shows the application of a capacitively coupled contactless conductivity detection (C4D) for monitoring biomolecular interactions on analytical microsystems. Initially, the analytical performance of the microsystems fabricated in glass, poly(dimethylsiloxane) (PDMS) and polyester-toner (PT) was investigated in order to choos

11. A generalized gas-liquid two-phase flow analysis for efficient operation of airlift pump
Airlift pumps are finding increasing use where pump reliability and low maintenance are required, where corrosive, abrasive, or radioactive fluids must be handled and when a compressor is readily available. The objective of the present study is to evaluate the performance of a pump under predetermined operating conditions and to optimize the related paramete
