  3. Abstract:
  4. Over the time, multistaging has proved to have some great benefits such as less electrical usage, so, nowadays; optimization of the electrical power usage in centrifugal compressors is an important issue to lead to the least usage of power. In this paper, we present a novel algorithm that provides this desire; it also shows different arrangement of the stages for the considered compressor. Simple single-stage compressor pressure ratio is normally limited by constraints of both aerodynamic and structural types. Reaching to minimum power leads to the least usage of electrical power. In this paper, we utilize theoretical relations which are extracted and have been presented a novel numerical approach to find optimized rp (pressure ratio) by using the least electrical power considering some initial constant data in multi stages centrifugal compressors. On the other hand, we can achieve to our optimum pressure ratio. A numerical method has been developed to show us the arrangement which this result will be gained. Certainly, the pressure ratio is achieved of our numerical method is higher than experimental result according to some our assumptions such as considering the gas as a perfect gas
