Fluid model calculations are a useful method to simulate the chemistry rich plasma sources often used in applications of cold atmospheric plasmas. Atmospheric pressure plasma jets provide plasmas that are not spatially bound to any electrode. Typically a plasma is generated internally and then convected to an ambient environment via a gas flow. In this work we outline preliminary models for mass transport of plasma species in the inter and outer electrode regions of a non-thermal atmospheric pressure plasma jet.

We use the plasma module coupled with the laminar flow and transport of diluted species modules in Comsol version 4.2 for simulation of the plasma jet.
