Electromagnetotoroid Structures and their Hydrodynamic Analogs
Mario J. Pinheiro
We introduce the concept of an electromagnetotoroid in astrophysics, and explore its role in polar jets. This model represents the onset of Abraham's force driven by some external…
On the influence that the ground electrode diameter has in the propulsion efficiency of an asymmetric capacitor in nitrogen gas
Alexandre A. Martins, Mario J. Pinheiro
In this work the propulsion force developed in an asymmetric capacitor will be calculated for three different diameters of the ground electrode. The used ion source is a small diam…
Study on the influence that the number of positive ion sources has in the propulsion efficiency of an asymmetric capacitor in nitrogen gas
Alexandre A. Martins, Mario J. Pinheiro
The present work intends to compare the propulsion force developed in an asymmetric capacitor, according to the number of positive ion sources used. The ion source is a corona wire…
Modeling of an EHD corona flow in nitrogen gas using an asymmetric capacitor for propulsion
Alexandre A. Martins, Mario J. Pinheiro
The present work intends to identify the nature of the propulsive force that occurs during a positive corona discharge in nitrogen gas using an asymmetric capacitor geometry. We ar…
Electrical and Kinetic Model of an Atmospheric RF Device for Plasma Aerodynamics Applications
Mario J. Pinheiro, Alexandre A. Martins
The asymmetrically mounted flat plasma actuator is studied using a self-consistent 2-DIM fluid model at atmospheric pressure. The computational model use the drift-diffusion approx…
Anomalous Diffusion at Edge and Core of a Magnetized Cold Plasma
Mario J. Pinheiro
Progress in the theory of anomalous diffusion in weakly turbulent cold magnetized plasmas is explained. Several proposed models advanced in the literature are discussed. Emphasis i…
Electron Trapping by Electric Field Reversals in Glow Discharges
Mario J. Pinheiro
The phenomena of electric field reversal in glow discharges is discussed. Several models are described and the link between the electric field reversal, electron's trapping and the…
EHD ponderomotive forces and aerodynamic flow control using plasma actuators
Mario J. Pinheiro
We present a self-consistent two-dimensional fluid model of the temporal and spatial development of the One Atmosphere Uniform Glow Discharge Plasma (OAUGDP). Continu…
The role of magnetic flux and wall current drain on anomalous diffusion
Mario J. Pinheiro
A theoretical analysis of the anomalous diffusion transport mechanism suggests a possible connection between wall current drain and magnetic flux through the orbital trajectories o…
Electron trapping by electric field reversal and Fermi mechanism
Mario J. Pinheiro
We investigate the existence of the electric field reversal in the negative glow of a dc discharge, its location, the width of the well trapping the electrons, the slow electrons s…
