Talk:Vlasov equation

Moment equations

I have added a section about momentum equations derived from the Vlaslov equation. It may be better to start a new article about fluid theory of plasmas or move it to plasma modeling or magnetohydrodynamics. What do other users think? --RockScient (talk) 17:53, 13 October 2008 (UTC)

In the present form the momentum section in this article is OK for me. If it will be significantly extended then perhaps it will be better to make a new article. But I am not an expert so please consider that you think more appropriate. It may be also helpful to include in this section explicit expressions in terms of f for the five mentioned quantities (density, velocity,...). --Tamtamar (talk) —Preceding undated comment was added at 07:53, 1 November 2008 (UTC).

Thank you for your comment. I have included the expressions for density, velocity and pressure. I have also removed any reference to temperature and heatflux since they don't appear in the continuity equation or momentum equation. RockScient (talk) 13:07, 16 November 2008 (UTC)

Could we elaborate on the "after some calculations" part while going from the kinetic equation to fluid equations? [User:Anjor] 11:14, 22 June 2009 —Preceding unsigned comment added by Anjor (talk • contribs)

Well, the calculation is straightforward, but it takes a lot of space. So, I don't know whether Wikipedia is the right place to present it. RockScient (talk) 14:42, 17 September 2009 (UTC)

I have added a section about the frozen-in approximation. I felt that this is so fundamental to plasma physics that it deserved to be mentioned. Unfortunately, I do not know the reference to the original work. The way I have presented it was shown to me by my professor in plasma physics. RockScient (talk) 01:48, 10 December 2008 (UTC)

I realized that the last part of this section was not entirely correct, and I have revised the text slightly. RockScient (talk) 14:42, 17 September 2009 (UTC)
