Hi community,

Is there someone how has experince with implementing vanes (IGVs) on a compressor unit in Simscape? From the default Simulink library the Turbine block has vanes, but this option is not available for the compressor (See attached picture).

Cheers

You are right about the compressor block: it doesn't support vanes as an input.

I can think of one workaround, by using a 3D lookup table:

The table is mdot(RPM,PR,Vane), which sent to an ideal mass flowrate source. Above is just an idea, and you'll need more details like density/temperature/pressure correction on the mass flow, adding heat for isentropic efficiency, etc.
