Turbomachines are devices that transfer energy between a rotating element and a fluid due to dynamic action, resulting in changes to the fluid's pressure and momentum. Turbomachines have various applications including fluid transfer, electrical power generation, and aircraft propulsion. They can be classified based on the direction of energy transfer, flow direction, fluid condition, and position of the rotating shaft. Principal components include a rotating element, stator, input/output shafts, and a housing. Modern turbomachines can generate over 250 MW of power and accommodate high pressures and temperatures.

2. What are Turbomachines?
A Turbomachine is a
device in which energy
transfer occurs
between a flowing fluid
and the rotating
element due to dynamic
action resulting in
change in pressure and
momentum of fluid.

3. Uses of Tubomachines
Turbomachines have
several applications
including
Fluid transfer
Electrical Power
generation.
Aircraft propulsion

4. Classification
I. On basis of Energy transfer
II.On the basis of direction of flow
III.Condition of fluid flow
IV.Position of rotating shaft

5. Principal Components of
Turbomachines
i. Rotating element carrying guideways.
ii. Stator.
iii. Input/Output shaft.
iv. Housing or Casing.

6. Mechanical Drawback
• Highly complex design.
• Thick walls for suffering high
pressure.
• Change in the fluid flow forces as a
independent of the vibration of the
rotor.
Blade
Vibration

7. Recent Development
• During 1940’s , tubines of 10 MW were
common.
• But today turbine of more than 250
MW are available with the industries.
• Pressures bearing upto 165 bar and
585°Caccomodate the limitation of
modern turbines.
