WebThe REFPROP v7.0 database is a shared library that is dynamically loaded into the solver when you activate one of the NIST real gas models in an ANSYS FLUENT session. Once the NIST real gas model is activated, control of relevant property evaluations is relinquished to the REFPROP database, and any information for a fluid that is displayed in ...
WebThe relative humidity is defined as the ratio of the mole fraction of water in the humid air to the saturation mole fraction of water. Because of the presence of air with the water, the pure water saturated vapor pressure must be multiplied by an enhancement factor that is very close to one near atmospheric conditions. Mathematically, the result is WebApr 2, 2024 · There are two equations of state available for air in Refprop, one is a mixture of nitrogen+argon+oxygen and the other is a pure fluid equation of state under the …
