Talk:Advection equation

I think a little elaboration might be helpful. What is psi? State explicitly. Also, compare to the equation of continuity: the advection equation looks the same.


 * It has been proposed to add this ENTIRE Wiki to the Advection article, as a section at the end, then delete it here. Why keep it separately?? And yes, it does still need cleaning up, as many of the variable used are not defined. S  B Harris 21:07, 18 April 2007 (UTC)
