The Effects of External Parallel Direct Current Magnetic Field on a Cold Atmospheric Pressure Argon Plasma Jet
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2014, Vol 8, Issue 7
Abstract
In this work, external direct current magnetic field effect on the atmospheric pressure plasma jet was investigated, experimentally. The magnetic field was produced using a Helmholtz coil configuration. It was applied parallel to the jet flow. The strength of the magnetic field was 0- 0.28 Tesla between the two coils in parallel application. It was shown that the plasma gas flow plays the main role in magneto-active collision-dominated plasma. The effect of plasma fluid velocity on the jet emission was discussed, qualitatively. It was observed that the external magnetic field has effect on plasma jet in parallel application. The measurements revealed that the plasma jet irradiance increases in parallel field. The former was attributed to increasing plasma number density and in turn shrinks plasma jet number density. As a result, it was concluded that the plasma fluid velocity is responsible for such trends though the magneto-active plasma remains isotropic.
