1. DBD Plasma: Explicit Model with Integral Approximate Solution to Wall Jet
ABSTRACT: This study aims to first introduce a formulation which is quite simple for obtaining dielectric-barrier discharge plasma spatial body force. This new model comprises a combination of an empirical model and a numerical one. Although there are still some limitations in the new model (restriction to specific geometry, maximum voltage amplitude of 30 k

2. 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

3. Effect of Dielectric Barrier Discharge on the Airflow Around a Cylinder
Abstract: Fluids in a dielectric barrier glow discharge at atmospheric pressure have attracted interest from communities of thermo and fluid dynamics, as well as control. This work investigated the effects of a plasma actuator, operating at 8.0 kV and 4.4 kHz, on the pressure distribution around a polyvinyl chloride circular cylinder in low-velocity airflow.

4. Flow control with EHD actuators in middle post stall regime
We analyze the modifications of the flow around a NACA 0015 airfoil when the flow is perturbed with an electrohydrodynamic (EHD) actuator. The device used consists of two bare electrodes flush mounted on the surface of the model operated in a discharge regime characterized by the formation of a plasma sheet contouring the body in the interelectrode space.

5. Obtenção e caracterização de filmes finos de oxido, nitreto e oxinitreto de silicio por deposição ECR-CVD / Synthesis and characterization of oxide nitride and silicon oxynitride thin films by ECR-CVD
In this work, silicon nitride (SixNy), oxide (SiOx) and oxynitride (SiOxNy) thin films obtained by remote plasma chemical vapor deposition (RPCVD) on silicon substrate were studied and characterized for micromachining or micro electro-mechanical system (MEMS) applications. Silicon nitride films (SixNy) were used in suspended structures (membranes and bridges
