Eine Methode zur Bestimmung der Viskosität eines Plasmas bei Atmosphärendruck

Abstract

In this paper a simple method is described to measure the viscosity of a plasma at atmospheric pressure: If spheres move through a cylindricel plasma perpendicular to the axis they undergo a deflection fmm which the resistance coefficient can be calculated. Measuring too the dynamic pregsure and the temperature and knowing the resistance Ooeficient aa function of the REYNOLDS number the viscosity can be computed. As an example the measurement of the viscosity of a nitrogen plasma is reported.
