Model for simulation of ion dynamics  in a dense gas and strong electric fields

A model that allows to simulate the dynamics of ions in a dense gas and in strong electric fields is presented. The method is based on a combination of the directed motion of an ion in a dense gas with adding diffusion component. The mobility coefficient based on the frequency of ion-molecular collisions depending on ion ve-locities is used. Through this mobility coefficient a coefficient of diffusion is described. Comparison of the re-sults of test calculations obtained with the help of the proposed method with the results obtained from the model taking into account individual ion-molecular collisions and a modified statistical diffusion model shows good accuracy of the method over a wide range of gas pressures and electric field strengths.
