1. Efeito da descarga de barreira dielétrica no escoamento do ar sobre um cilindro / Effect of dielectric barrier discharge on the airflow around a cylinder
Fluids in a dielectric barrier DBD glow discharge at atmospheric pressure attracted the interest of the communities of thermo and fluid dynamics as well as control. This dissertation investigates the effects of a plasma actuator operating at 8 kV and 4.4 kHz, on the Cp curve of a PVC cylinder in a low velocity airflow. The experiment was repeated with the ac

2. DESENVOLVIMENTO DE MÉTODOS ANALÍTICOS CROMATOGRÁFICOS, ESPECTROFLUORIMÉTRICOS E ELETROFORÉTICOS PARA A DETERMINAÇÃO DE AZAARENOS BÁSICOS EM QUEROSENE DE AVIAÇÃO / DEVELOPMENT OF ANALYTICAL METHODS BASED ON CHROMATOGRAPHY, FLUORESCENCE AND ELECTROPHORESIS FOR THE DETERMINATION OF BASIC AZAARENES IN JET FUEL SAMPLES
In this work, analytical methods were developed for the selective determination of basic azaarenes. Solid phase extraction (SPE) in combination with high performance liquid chromatography with fluorescence detection (HPLCFD) has been used for the sensitive method determination of six basic azaarenes (7,8-benzoquinoline - 78BQ, 7,9-dimethylbenz[c]acridine - 7

3. Studies on the cooling minimum quantity and conventional cooling at hardened steels in grinding process
The purpose of this work is to explain the concept of cutting fluids reasonable usage through the fluid minimum quantity in grinding processes. On that purpose, the development of a new nozzle and an own and adequate methodology should be required in order to obtain good results and compare them to the conventional methods. The analysis of the grinding wheel

4. Numerical study of synthetic jet actuator effects in boundary layers
This work has as a fundamental objective the numerical study of the effects of synthetic jet actuators on the flow of the boundary layer developed on a flat plate and on a hypothetical airfoil. The aim is to obtain computational data to indicate how these effects may be used as a means of flow control, describing the dynamics of the synthetic jet in the pres

5. Study of the effects of a numerically simulated synthetic jet on the delay of separation of the boundary layer on a hipothetical airfoil / Estudo dos efeitos de um jato sintético simulado numericamente no atraso da separação de uma camada limite sobre um aerofólio hipotético
A realização deste trabalho tem como objetivo fundamental estudar os efeitos dos atuadores de jato sintético no escoamento de uma camada limite desenvolvida sobre uma placa plana e um aerofólio hipotético. A interação dos jatos sintéticos com um escoamento transversal pode conduzir a uma aparente modificação da forma aerodinâmica de corpos rombudo

6. Pulmonary Evaluation of Permissible Exposure Limit of Syntroleum S-8 Synthetic Jet Fuel in Mice
No current studies have systematically examined pulmonary health effects associated with Syntroleum S-8 synthetic jet fuel (S-8). In order to gain an understanding about the threshold concentration in which lung injury is observed, C57BL/6 male mice were nose-only exposed to S-8 for 1 h/day for 7 days at average concentrations of 0 (control), 93, 352, and 61
