MHD energy equation

  1. Aug 17, 2009 #1
    Is this the right format of the energy equation (equation 2.10)?



    I know it in a different format:

    \frac{dp}{dt}+\gamma p\nabla\cdot\mathbf{v}=-L

    Where is the difference coming from?

    Hi MasterD! :smile:

    Isn't your second equation the case for ρ = constant (and with D/Dt being the convective time derivative, ∂/∂t + v.)?

    Thanks for your reply Tim. [tex]\rho[/tex] is not constant, however.. D/Dt is indeed the convective time derivative.
