Abstract We have shown that measuring the surface tension is a useful scheme to examine the plasma-liquid interface in real-time. The surface tension was measured using a method based on the dispersion relation of an acoustic capillary wave excited on the water surface. The surface tension gradually increased with time, when the water surface was irradiated with the outside region of the spatial afterglow of an atmospheric-pressure plasma. The Marangoni effect associated with the localized increase in the surface tension was observed during the plasma irradiation. The surface tension decreased after the termination of the discharge. A correlation was found between the transient decrease in the surface tension and the variation of the OH radical density in the gas phase. No increase in the surface tension was observed in the solution containing a trapping agent for liquid-phase OH radicals. These experimental results suggest that OH radicals act to increase the surface tension. However, the behavior of the surface tension cannot be explained perfectly by considering only the action of OH radicals.

Carbon Erosion

AbstractThe erosion of soot by oxidation in a non-thermal, atmospheric pressure plasma has been modelled using a simplified, two layer, kinetic scheme for the surface reactions coupled with a gas-phase reaction mechanism that is appropriate to diesel exhaust gas. Experimental measurements of the rate for carbon erosion and the evolution of CO and CO
