In a low speed, single stage (a pair of rotors) counter rotating fan or compressor, can flow coefficient be equal to or greater than 1?

19 February 2014 1 687 Report

For inlet axial velocity / tangential velocity of the rotor. Such high values does not occur in a conventional low speed single stage compressor (rotor and stator).

Rohit Adhav

I feel it is possible. If you normalize the flow coefficient based on the design point it is possible to have coefficient more than 1. For instance, say compr is working at 120% load or so. This is applicable provided Mach no
