Talk:Euler equations

From Wikipedia, the free encyclopedia

should I put stuff about Rankine-Hugoniot conditions here or under shock waves?

Mo ena ene test lor eulers la. Ki pou fou????


Is it possible for someone to define all the variables in this article? Rtdrury 10:59, 19 December 2005 (UTC)



As an answer to : "in particular, it is not intuitively clear why this equation is correct and :\left(\partial/{\partial t}+{\bold u}\cdot\nabla\right)(\rho{\bold u})+\nabla p=0 is incorrect" : the reason is simple enough, Newton's second law states Force=mass*(derivative of u) not Force=derivative of (mass*u), where u is the velocity, therefore it is clear that the formula given above cannot be correct if the mass density is not constant (like in the flow of a compressible medium). This is a common misconception of Newton law, which for example leads to incorrect results for the eqution of motion of rockets. Gringo.ch 10:44, 3 October 2006 (UTC)
