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 On basis of Energy transfer On the basis of direction of flow Condition of fluid flow Position of rotating shaft

5. Principal Components of Turbomachines Rotating element carrying guideways . Stator. Input/Output shaft. 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.
