Abstract
We propose a structure of integrated micro solution plasmas, in which a number of microplasmas can be generated in a liquid medium, and we can expect efficient plasma-liquid interaction. It consists of a non-isolated porous dielectric material filled with a gas-liquid mixed medium. Since the bubbles in this structure are surrounded with conductive liquid, electrical discharges in the bubbles are not expected if we use liquid with infinite electrical conductivity. However, numerical simulation has revealed that the electric field in the bubbles can be high enough to ignite atmospheric pressure discharge in it if the liquid has finite electrical conductivity, for example 200 uS/cm for typical tap water, and that the concept of the integrated micro solution plasmas is feasible one.
