Aspen compressor simulation, surge point issue
Thread Content
Use Aspen for compressor modeling. The performance curves of the compressor were entered (power-flow curve, multi-stage efficiency-flow curve). The runtime result warns that the flow rate is below the surge point. May I ask how the surge point in the software is determined at this time? I did not enter the surge curve.
It is estimated that the flow rate is below the minimum flow rate specified in the current speed-performance curve you entered. This point should be set as the surge point by default
