The Biefeld-Brown Effect: Misinterpretation of Corona Wind Phenomena
Originating from the early 1920's, the so-called Biefeld-Brown effect claims the generation of thrust in capacitor configurations exposed to high voltage. This thrust was claimed to be not due to corona wind phenomena and also exists in vacuum. These claims, although only published in patents, survived until recent publications for very advanced propulsion concepts. This paper reviews Brown's a...
متن کاملIon Cyclotron Damping in the Solar Corona and Solar Wind
The solar corona is the hot, ionized outer atmosphere of the Sun. Coronal plasma expands into interplanetary space as a supersonic bulk outflow known as the solar wind. This tenuous and unbounded medium is a unique laboratory for the study of kinetic theory in a nearly collisionless plasma, as well as magnetohydrodynamic waves, shocks, and jets. Particle velocity distributions in the solar wind...
متن کاملComposition Variations in the Solar Corona and Solar Wind
Order of magnitude variations in relative elemental abundances are observed in the solar corona and solar wind. The instruments aboard SOHO make it possible to explore these variations in detail to determine whether they arise near the solar surface or higher in the corona. A substantial enhancement of low First Ionization Potential (FIP) elements relative to high FIP elements is often seen in ...
متن کاملMultiphysics simulation of corona discharge induced ionic wind
Ionic wind devices or electrostatic fluid accelerators are becoming of increasing interest as tools for thermal management, in particular for semiconductor devices. In this work, we present a numerical model for predicting the performance of such devices, whose main benefit is the ability to accurately predict the amount of charge injected at the corona electrode. Our multiphysics numerical mod...
متن کاملObserved Associations between the Solar Interior, Corona, and Solar Wind
Using polarized brightness (pB) measurements made by the High Altitude Observatory (HAO) Mauna Loa Mk III K-coronameter, we investigate the daily changes of path-integrated density at 1.15 R,. During 1996, when simultaneous pB and helioseismology data were available, we find that the correlation of pB (at zero time lag and 207 latitude lag) varies with latitude in the same way that the subsurfa...
