Session 7P - Plasma Applications and Plasma Technology.
POSTER session, Thursday morning, November 14
Exhibit Hall - Concourse Level, Adam's Mark
We have generated a steady-state glow discharge plasma at atmospheric pressure and have conducted parametric studies by varying the input voltage and RF frequency. This one atmosphere uniform glow discharge plasma^1 reactor developed at UTK can be used in industry to treat surfaces at low cost. A parallel-plate configuration has been used to sterilize and to treat the surface of materials and a flat-plate configuration has been used to affect the aerodynamic boundary layer and skin friction drag. The voltage and current waveforms as functions of time are used to measure the input power. In the past we have found that the relationship between the input power versus the applied voltage and frequency in log-log scale is P \propto V^3 and P \propto f^2. This paper compares the functional dependence of the power dissipation per unit area of these two configurations.
