1. A turbine of an air cycle machine, comprising:
a housing;
an output shaft that spins about a spin axis;
a turbine disposed on the output shaft;
a first nozzle defining a first inlet area that is configured to direct a first flow into the housing, the first nozzle extending along a first axis that is disposed at a first meridional angle to the spin axis;
a second nozzle defining a second inlet area that differs from the first inlet area, the second nozzle is configured to direct a second flow into the housing to provide a mixed flow within the housing, the second nozzle extending along a second axis that is disposed at a second meridional angle to the spin axis, the second meridional angle differing from the first meridional angle; and
a control valve configured to open and close the second nozzle.
