MATLAB: How to model a time dependent “specific heat” in a simulink/simscape Gas Properties Block

Question

Is there a posibillity to read new parameters to a Gas properties block in simscape depending on other simscape subsystems at every timestep? I have to model a filling process with different gases to mix, what i basically do with different gas subsystems, but the parameter of the mixed gas flow depends on output, calculatet at every timestep.

Answer 1

While this would be challenging with the Gas domain, consider using the Moist Air domain. While the name is Moist Air, it is essentially a three-species gas domain which allows condensation in one of the species. One could specify the properties of the second gas as a Trace Gas and add appropriate sources. This would cause your overall fluid properties to change with changing concentrations.
