| Popis: | An equation of state is a thermodynamic equation relating fluid properties which describe the state of matter under a given set of physical conditions. Considering there are some connections between the properties of different fluids, we believe there are some corresponding relations between the critical heat flux (CHF) of different fluids. A corresponding principle was developed to predict the critical heat flux with the experimental data obtained with modeling fluids. A series of scaling criteria were developed on the basis of fluid similarity and molecular thermodynamics, which is totally different from the conventional scaling methods based on experimental data and empirical correlations. The prediction error of this principle is much lower than conventional prediction methods. The average and maximum error of the corresponding principle is about 10%. |
