基于Boltzmann方程的TLEs电子分布特性研究
Research on Characteristics of Electron Energy Distribution Function of TLEs Based on Boltzmann Equation
摘要
Abstract
Transient Luminous Events ( TLEs) in the upper atmosphere is a focus of near space,to solve the Electron Energy Distribution Function (EEDF) is the key to research the TLEs’ problems of the radiation characteristics,the disturbed electron density and so on. Based on the numerical model of Boltzmann equation,the time evolution of the EEDF is calculated;combined with the only variable prin-ciple,found that many parameters,such as the time step ( δt ) ,the grid interval of electronic energy ( △ε) ,reduced electric field ( E/N) , atmospheric pressure ( P ) ,atmospheric temperature ( tgas ) and initial electric average energy of Maxwell distribution ( tel ) ,have influenced on EEDF and its regularity. Under the complicated environment and the changing electric field in the actual in order,how to solve the EEDF of the gases in TLEs to get more accurate result using the numerical model of Boltzmann equation are identified.关键词
