Hi,

May i know in which Openfoam solver will i get the following equation:
Why different solvers using navier stroke's equation have different momentum and energy equations? The navier stroke's equation should be same for all solvers right?

Equations may differ because a different energy is used. For example some use inner energy while others use enthalpy. Also, some solvers are compressible while others are incompressible.

reactingFoam can be the nearest choice, but without term #2 in RHS (sum h_j J_j)

But, if you will solve energy in enthalpies and assume Le number equal to 1, then term #2 in RHS will become compensated by enthalpy diffusion term
