Hybrid simulation of interaction between electron-beam-generated plasmas and air flow

Summary form only given. A 2-D Hybrid numerical model was set up to simulate the process of interaction between large-volume electron-beam-generated plasmas and air flow. High energy electrons were simulated by Monte Carlo numerical method. Low-energy electrons and the ions species excited by collisions were considered by fluid model and simulated by finite-element method. It shows that the air flow can affects the space distribution of low-energy electron density by the convection and transport of ions species. And the influence of the electron beam to the air flow field is only existed in small-scale phenomenon. The velocity field of the far-field air flow is disturbed below 1%. But the electron beam have important effects on the property of boundary layers and the turbulent intensity of the fluid field.
