Ion drag heating
WebThe thermosphere is subject to additional electric and magnetic forces, not important in the middle and lower atmosphere, due to its partially ionized atmosphere. The effects of charged particles on the neutral atmospheric dynamics are often parameterized by ion drag in the momentum equations and Joule heating in the energy equation. Presented in this paper … Web14 dec. 1994 · A comparison is made of the forces governing the transport of negatively charged particles electrostatically suspended in the plasma of a symmetric parallel-plate radiofrequency glow discharge with isothermal walls. The two forces driving the particles symmetrically from the plasma centreline to the sheath edges are the ion drag force and …
