Hello everyone!

I want to model a Brayton cycle in simscape.

Can I not use the compressor(2p) in the simscape library? Instead, I can use the Compressor module in the example sscfuids ev thermal management/Compressor , and then adjust his Compressor Map coefficients, is this possible?

Since I don't have compressor data, I just continue to use his Compressor Map, is the simulation result reliable? Or is there a better solution?

Thanks!

Hi @runyi xu,

The "Compressor(2p)" block in the simscape library uses both "Analytical" and "Tabulated" data to model the block. To visualize the block map based on the parameter right-click the block and select Fluids > Plot Compressor Map.

The Compressor block can be used by using the default block parameters to model the brayton cycle and can be parameterized based on the reqirements of the model.

The below simulink model of "Brayton Cycle(Gas Turbine) can be used as a reference

I hope this would resolve the issue.
