Abstract
In this mathematical work, we provide a prediction and simulation of the
behavior of the axial compressor system under the circumstance of
increasing and recycling the stall and surge by using numerical analysis.
The Moore-Greitzer model was programmed and the influence of the
compression system parameters (compressor length, the initial value of
stall amplitude, velocity parameter B) on the surge and rotating stall was
investigated. The results were compared with published data for the
validating of the code.
Also, was developed a mathematical program to include the inlet
distortion model to study the effect of inlet distortion on the surge and
rotating stall behavior. The results show that the higher values of velocity
parameter B lead the-system to surge cycles, while its lower values leads
it to rotate stall region.
Smaller values of compressor length cause a large excursion in amplitude
of the stall. By increasing the initial value of the amplitude of stall it takes
a short time to reach the steady state. The small value of inlet distortion
does not change the stall behavior while the largest value of inlet
distortion leads the system to entering to modified surge cycles.
