It is now possible to simulate with real-gas equations of state. Details on the physics and the setup can be found in the documentation article for Thermophysical Fluid Models. When choosing a real-gas you must provide data of the density and enthalpy as functions of temperature and pressure (see image below). You can also provide the viscosity as a function of temperature and pressure.
You can find this data for many different fluids in user-specified temperature and pressure ranges in the Chemistry Webbook of the National Institute of Standards and Technology (NIST).
Yes, simulating with real-gas equations of state is now possible in some simulation software. The implementation of real-gas equations of state allows you to model the behavior of gases under conditions that deviate from ideal gas behavior.
In order to use real-gas equations of state, you need to provide data on the density and enthalpy of the gas as functions of temperature and pressure. In some cases, you may also need to provide data on the viscosity of the gas as a function of temperature and pressure. This data can be obtained from experiments or from thermophysical property models.
Once you have the required data, you can input it into the simulation software and configure it to use the real-gas equation of state. The software will then use this information to model the behavior of the gas under the specified conditions.
It is important to note that the accuracy of the simulation results will depend on the quality and accuracy of the data used to describe the real-gas behavior. Therefore, it is important to carefully validate the input data and to ensure that it is appropriate for the conditions being simulated.
