On the shuttle glow the plasma alternative
نویسنده
چکیده
It is shown that the anomalous glow observed in the recent space shuttle flights can be attributed to a combination of beam plasma discharge and critical ionization phenomena. While the shuttle velocity (~8 km s -x) is below the critical ionization velocity, which for oxygen is 12.7 km s -x, specular reflection of a small fraction (2-3%) of ambient ions forms an ion beam with velocity 16 km s -x, making up for the energy deficit in the critical ionization velocity phenomenon. The wave activity observed is consistent with this model.

ABSTRACT In this work, the dry reforming of methane was studied using a corona and glow discharge plasma microreactors. A chemical kinetic model was developed to understand the reaction better. The modelization allowed prediction of the reactants conversion according to the energy transfer to the gas (P×τ). The β value is trait of the energy cost, whatever this value was leeser indicated ...

2014 Spatially resolved spectroscopic diagnostics such as plasma-induced emission, laser-induced fluorescence and laser optogalvanic spectroscopy are used to characterize the cathode sheath and the negative glow of an abnormal glow dc discharge in nitrogen. These diagnostics provide local information on the excitation and ionization functions, on the concentrations of ions and on the rotational...
