1. Obtenção de equações de desempenho de difusores de ar / Obtaining performance equations of air diffusers
O presente trabalho procura encontrar equações representativas do desempenho de difusores. Essencial nos sistemas de distribuição de ar-condicionado, os difusores atualmente são selecionados por intermédio de gráficos de desempenho. Pelo método dos mínimos quadrados, foram ajustadas equações que descreveram o comportamento destes gráficos. Os res

2. Análise da acetona em ar exalado: metodologia para estudo em pacientes hospitalizados / Breath Acetone Analysis: Methodology for studying hospitalized pacients
The dissertation fits in the research field of noninvasive clinical analysis, more specifically, the prognosis of the severity of heart failure, HF, based on a biomarker found in the air exhaled by patients, in a study at InCor-HCFMUSP. The most relevant biomarker found by GC-MS was acetone (propanone). For the breath collection a device was developed which

3. CFD analysis of laminar axisymmetric diffuser flow.
In this current work it is presented the two-dimensional axisymmetrical air flow simulations under laminar regime in a conical diffuser using Computer Fluid Dynamics (CFD). The use of diffusers in laminar flow can be seen in micro-pumps applications, especially for micro-electronics cooling. The objective is to analyze the static pressure recovery coefficien

4. Optimizing dissolved air flotation design system
Dissolved Air (Pressure) Flotation-DAF, is a well-established separation process that employs micro-bubbles as a carrier phase. This work shows results concerning bubble generation at low working pressures in modified DAF-units to improve the collection of fragile coagula by bubbles. DAF of Fe (OH)3 (as model) was studied as a function of saturation pressure
