Compressible navier stokes
Hi all
I need a correct equation for compressible NS I see the equations are different The density in momentum equations are treated differently e.g:: rho*u1*du1/dx+rho*u1*du2/dy+.... but in another equation d(u1*rho)/dx+..... Why they are different? Thanks in advance , Selim |

Hi,
I guess you are refering to the convective term in the momentum equation? If so, you can use the continuity equation to move from one formulation to the other.. |
