TURBO MACHINES

I have been thinking to post technical articles on variety of topics related to mechanical industry, it may be steam turbine, pressure vessels, material joining, ndt, corrosion, Inspection tactics for Source & In-service inspection of stationary & Rotary equipment's & so on. And i am taking this opportunity with Steam Turbines.
Let start from Turbo Machines ....
Turbo machines are fluid machines that are based on a spinning rotor, The rotor will typically have blades, deflectors, or buckets on it to effect interaction with the fluid.
The word turbo or turbines is of Latin origin and implies that which spins or whirls around.
Turbines, compressors and Pumps are all members of the same family of machines called turbo-machines.
A turbo-machine is a power or heat-generating machine, which employs the dynamic action of the rotor, the action of the rotor changes the energy level of the continuously flowing fluid through the turbo-machine.
Two main categories of turbo-machine :
Generate power by expanding fluid to a lower pressure (Gas, Steam & Hydraulic turbines)
Steam Turbine -
Hydel turbine -
Gas Turbine -
And another one is absorb power to increase the fluid pressure or head (Compressors and Pumps)
Compressor
Centrifugal Pump
Will meet on next article.....
