In aircraft design and engineering, the efficiency of a centrifugal flow compressor is a measure of how effectively the compressor increases the pressure of the incoming air while minimizing losses. It is typically expressed as the isentropic efficiency, which considers the idealized (isentropic) compression process.
The isentropic efficiency (η_isen) of a centrifugal flow compressor can be calculated using the following formula:
- η_isen is the isentropic efficiency, a dimensionless quantity.
- Actual Work Done represents the actual work required or done by the compressor during compression.
- Isentropic Work Done represents the work that would be required or done if the compression process were perfectly isentropic (reversible and adiabatic).
