Factors Influencing the Performance of Porous Wind Shields [PDF]

Applied Mechanics and Materials, 2013
Porosity, porosity distribution, porous shape, porous size, thickness of shield, shield height &width, and shield orientation are the factors that influence the performance of porous wind shields. Among them, porosity is the most important factor in determining the performance of porous shields.

Power laws and self-similar behavior in negative ionization fronts

, 2005
We study anode-directed ionization fronts in curved geometries. When the magnetic effects can be neglected, an electric shielding factor determines the behavior of the electric field and the charged particle densities.
