compressor from lower pressure into higher pressure. Compressors working in a small pressure ratio can also be referred as blowers. In this study, a centrifugal compressor designates a kinetic compressor working in one phase, keeping the rounding speed of the fluid mainly radial.
tutorial on principles of operation and performance estimation of centrifugal compressors 163 where D, H, V, N are, respectively, diameter of the impeller, head, velocity, and speed of the machine.
machines. Axial and centrifugal compressors draw their names from the primary direction in which the flow moves within the compressor. Axial compressors (Figure 2) handle much higher flowrates than centrifugal compressors, but generate lower pressure ratios. Modern centrifugal compres-sors accommodate lower flowrates than axial compressors
In this study, the compressor pressure ratio and rotational speed prediction performance of three compressor models, including the newly proposed compressor model based on
Abstract: The optimum pressure ratio for the stages of a multistage compression process is calculated with a well known formula that assigns an equal ratio for all stages, based on the hypotheses that all isentropic efficiencies are also equal.
Tutorial on centrifugal compressors. The centrifugal compressor performance characteristics can be derived in the same way as an axial compressor. Performance is evaluated based on the dependence of pressure ratio and efficiency on the mass flow at different operating speeds.
Centrifugal compressors can develop higher per stage pressure ratios. Schematic of a typical centrifugal compressor. Typical centrifugal compressor rotors. The torque applied on the fluid by the rotor τ = m [ ( rC ) − ( rC. w ) 2 w 1 ] , where 1 and 2 denotes the compressor inlet and outlet, respectively.
