Answer Posted / guest
Turbine shaft material has its own natural frequency, when
turbine rotates on such a speed that frequency of shaft
become close to its natural frequency, machine causes noise
& high vibrations because of resonance due to matching of
frequency. Running of Steam "TURBINE" on this speed is
avoided & this is called Critical speed. A turbine may have
more then one critical speed, which may depend upon number
of couplings.
it is denoted by w(omega).
