A turbo machine is a device in which energy transfer occurs between a flowing fluid and rotating element due to dynamic action.
This results in change of pressure and momentum of the fluid.
The word turbo or turbines is of Latin origin, it means which spins or whirls around. power generating turbo machine.
A turbomachinery stage comprises a row of fixed, guide vanes called stator blades, and a row of rotating blades termed rotor.
To elevate the total pressure of a working fluid, compressor stages are used that partially converts the mechanical energy into potential energy.
Turbomachinery, in mechanical engineering, describes machines that transfer energy between a rotor and a fluid, including both turbines and compressors.
While a turbine transfers energy from a fluid to a rotor, a compressor transfers energy from a rotor to a fluid.
