Hi everyone!
Looking through the forum titles I couldn't find a better place to put this question, so I'm going to ask here. If it should be somewhere else, let me know and I'll move it. Does anyone know where I can find the IAPWS supplementary backward equations that are functions of 1. Temperature and enthalpy; f(T,h) and 2.Temperature and entropy; f(T,s). Thanks in advance! |

because of the non-linearity of relations, I believe that no such equations can exist.
I had the same problem for my two phase code. I used some iterative method to solve the problem. But the computational cost is really annoying. |

Yeah, that's why we want to find the backwards equations. We have found a number of the other backwards equations just looking through the ASME website at other publications, but the aforementioned ones eluded us. Thanks for the reply!
