Hi guys
I'm doing with plasma and Cp varies with T and P. Does anyone knows how add pressure dependence in DEFINE_SPECIFIC_HEAT? if it was dependent to only T it was easy, but now with T and P dependence i think UDF will work. Does anyone have any suggestion? Thanks alot |

Hello,
The answer is late and would not be useful for you, but I am writing to others probably. It is written in fluent UDF guide V18 nodding that it can be temperature dependant only: "The DEFINE_SPECIFIC_HEAT macro can be used to define temperature-dependent functions for specific heat and sensible enthalpy for fluid, solid and mixture materials" I tried to write it based on pressure and there was an error during the compilation. it was discussed in the following link with apparently the same conclusion: temperature and pressure dependent specific heat? |

hi...Thanks for your reply.
But we did it by means of User-Defined Real Gas Model. Check here to get more informations. https://www.afs.enea.it/project/nept...ug/node337.htm All the best Amirreza |
