why compressible flow solving isnt need energy Eqn

July 19, 2003, 13:58

I use CFDRC , its flow module use only continuity and momentum eqn. When solveing a residual plotter show a graph of u,v,w,p,k,epsilon (use k-epsilon). so i wonder how its compute compressible flow? which add more 2 variable: T and roh without energy eqn....

thanks

It is possible that it assumes constant stagnation enthalpy and igonores conduction, then the energy equation reduces to an algebraic equation that is solved between steps. That is how i did my compressible euler equation code.
