Can anybody direct me to an article / book on how to treat enthalpy based energy equation in numerical solution.
any help is appreciated.

I think you should state your question a little more specific. Do you:
> need information on the actual statement of the enthalpy based energy equation? > need information on discretisation for FV/FD/FE methods? > need information on the actual solution of the resulting system of equations > need other information, etc. ... Right now from what I assume is that you need general information on this topic, so I would recommend books that cover all the questions above. A good start would be "Computational Fluid Mechanics and Heat Transfer" by Richard H. Pletcher. http://iate.oac.uncor.edu/~manuel/li...20Anderson.pdf If you get more specific with your question it might be easier for other users to give recommendations.

I have written a working SIMPLE code which uses temperature based energy equation, I want to change that to entalpy/temperature based energy equation.

you can use the equation for the total energy rho*(Cv*T + V^2/2), the advantage is that you can use the conservative form

I don't know about this kind of problem but I am quite confident you can define a specific total energy of the supercritical fluid system by defining properly the internal energy from your multiparameter equation of state
