Summary
The electron distribution function, the electron temperature and some transport parameters (electrical conductivity and energy flow coefficient) are obtained starting from the nonlinear Boltzmann equation for a plasma under the action of an external electric field. The Fokker-Planck approximation is used for electron-electron and electron-ion interactions. The effects of electron-electron collisions are studied for different values of collision frequencies and electric field.
Riassunto
La funzione di distribuzione degli elettroni di un plasma su cui agisce un campo elettrico è ricavata, unitamente alla temperatura elettronica e ad alcuni parametri di trasporto (conducibilità elettrica e coefficiente di flusso di energia), partendo dall'equazione non lincare di Boltzmann. Le interazioni electtrone-elettrone ed, elettrone-ione sono espresse nell'ambito dell'approssimazione di Fokker-Planck. Gli effetti degli urti elettrone-elettrone sono studiati per differenti valori delle frequenze di collisione e del campo elettrico esterno.
Резюме
Используя нелинейное уравнение Больцмана для плазмы при наличии внешнего электрического поля, получаются электронная функция распределения, электронная температура и некоторые транспортные параметры. Используется приближение фоккера-Планка для электрон-электронного и электронионного взаимодействий. Исследуется влияние электрон-электронных соударений для различных значений частот соударений и электрического поля.
