Hi Rob,nThank you for your response. In principle, I do not have any problem with the models available at ANSYS Fluent. The issue is that any of these models is valid for my problem, so I have decided to implement a custom multiphase model by means of User-Defined-Scalars and User-Defined Real Gas Models. nThis custom model depends on some parameters, and the value of a parameter arising in the equation of energy is missing. In order to set an appropriate value, I am looking for experimental results.nThank you,nAitorn
