The transport of H 2 O and OH from an atmospheric pressure plasma jet to a liquid sample are investigated using multiple detection techniques plasma-chemical global model. Scaling formation pathways species presented discussed.
Abstract The transportation of plasma-generated species through a liquid environment is key step within the plasma-driven biocatalysis process, but also great importance for other systems with plasma-liquid interfaces. aim this study to explore processes and lifetime in an aqueous solution. Therefore, combination experimental methods, reactive molecular dynamics simulations, reaction-diffusion modelling was used. Experimentally, atmospheric pressure plasma jet used treat sample. Convective...
The process of deriving fluid equations from the Vlasov equation for collisionless plasmas involves a fundamental challenge known as closure problem. This problem consists fact that temporal evolution any particle moment—such density, current, pressure, or heat flux—includes terms depend on next higher-order moment. Consequently, truncating description at nth order necessitates approximating contributions (n+1)th moment within choice truncation level and assumptions...
In computational plasma physics kinetic models are used to simulate phenomena where small scale is expected be of importance. These contain the full information particle velocity distribution function but computationally expensive. Therefore, cheaper utilized, which can then deployed larger scales e. g. 10-moment fluid or magnetohydrodynamics (MHD). However, large behavior critically influenced by behavior. For example, solar wind observations show that ion and electron instabilities...
Abstract A humid atmospheric pressure plasma jet was used to treat an aqueous liquid. The transport of hydrogen peroxide and hydroxyl from the liquid analyzed. Two in situ diagnostics for each species were compared validated. In case H 2 O , a spectrophotometric approach using ammonium metavanadate electrochemical sensing based on Prussian blue carbon paste electrodes applied. Both methods show very good agreement trends absolute values. detection OH performed by terephthalic acid (TA)...
