Shadow method for measuring the electron density in a barrier discharge plasma on the Zhukovskii airfoil surface

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

We have measured the electron temperature and density distributions in an ionized gas flow initiated by a high-frequency barrier discharge on the Zhukovskii airfoil surface by the method of photometry of shadow patterns for two probe radiation wavelength λr = 0.675 μm and λb = 0.425 μm. The investigation was carried out in air at atmospheric pressure. The maximum value of the electron density was N e ∼ 2.2⋅1015 cm−3 with an insignificant change in the air temperature in the discharge gap.
