Transient - Speed vs. Time
Certain configurations of a compressor allow the direct specification of Speed vs. Time.
Transient Data
For Speed vs. Time, the variation of speed must be directly defined in Transient Data. The speed of the compressor will be forced to meet this data at each time step of the transient simulation, with the compressor curves being adjusted every time step according to the affinity laws.
