The main purpose of this paper is to evaluate the results of multiple simulation methods and verify them with results of experimental measurement. Therefore, this paper presents three different models, a partial differential equation system, an analytical calculation and a model based on plasma physics. With these models, it is possible to calculate ion currents as a function of voltage and air pressure. The simulated data are compared with each other and evaluated with the focus of accuracy. Furthermore, the simulation results are verified by experimental data. The coaxial experimental setup with the possibility to variate voltage and air pressure is presented. This setup is used to create the measurement data for the model verification.
