Research Abstract |
Results of this study are completion of a theoretical model for describing a rectilinearly channeled negative surface discharge. They are given as under. 1. A nonlinear diffusion equation in the channel holds varied. The boundary conditions at the channel tip were based on the condition of current continuity and the condition that the propagation speed is proportional to the gradient of second power of the tip potential. 2. Those two boundary conditions clearly delineate that the tip potential is constant. 3. Application of an appropriate scaling of relevant quantities enable uniquely determining a one-parameter family of general solutions of a nonlinear diffusion equation and applying the tip potential to the analytical solution subsequently gave the relation between the applied voltage and the length. Finally use of the length allowed deriving the potential distribution above the channel. 4. The channel tip potential is proportional to the thickness in the range of 25〜75μm. 5. It became clear that the relationship between the three propagation parameters that is the tip potential, the electron mobility of the channel and the propagation characteristics on basis of the analytical solution of the non-linear diffusion equation. 6. We analyzed several data obtained by different experimental system 7. Applying the experimental data to the theoretical solution, we proposed propagation start condition and propagation stop condition for model.
