The SANA code performs a detailed two-dimensional analysis by means of throughflow calculation with allowances for losses in axial-flow multistage compressors and turbines.
This paper deals with (i) the experimental analysis of the unstable response of a multistage compressor during surge conditions and ii) the development and tuning of a nonlinear model for simulating the dynamic behavior of the compression system.
Thus, the vaporized ammonia in tank A is liquefied and stored in tank A. Once the pressure of ammonia gas in the tank is increased by the multistage compressor, the compressor stops, and thus, liquid ammonia in tank A is vaporized.
During the operation, the gaseous ammonia obtained from liquid ammonia is compressed and then liquefied by the multistage compressor.
Transfer of ammonia to tank B can be accomplished by various methods; however, the best option when using the present system will be to feed compressed and liquefied ammonia from the multistage compressor.
The use of a speed increasing gear box enables the specific speed to be increased and therefore resulting in higher efficiency and less complexity than would be obtained with a multistage compressor design approach.
Temperature in the multistage compressor (K).
This chapter examines the effects that multistage compressor configurations have on the overall compressor performance curve.
This discovery is valuable for the study of multistage compressor matching problems at off-design conditions.
Any multistage compressor is designed on the basis that succeeding impellers will compress a lower volume flow resulting from the compressibility of the specific gas handled.
