Moment equations edit
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)
