What are the different types of turbine used in Fluid machinery ?

INTRODUCTION

 Turbines are defines as the rotating mechanical devices that convert the energy of a water or a fluid into some useful work by conversion of this energy into mechanical power or energy .Sometimes this energy is also used for the generation of electricity .There are different types of hydraulic turbines  used in the fluid machinery on the basis of net head used ,specific speed and on the basis of whether it is impulse  or a reaction turbine .First of all ,let us understand what is impulse and reaction turbine .

IMPULSE TURBINE 

 The impulse turbine is defined as the type of turbine which requires only the virtue of its kinetic energy to rotate its fluid .The most perfect example of the impulse  turbine is the Pelt-on wheel turbine which is a tangential flow impulse turbine .The impulse turbines are used in the cases where the high head of water and low discharge is  required for the power conversion is required .

REACTION TURBINE 

 The reaction turbine is defined as the type of turbine which requires the virtue of both the pressure energy and the pressure energy to rotate its fluid .The most perfect examples of reaction turbine are Francis Turbine ,Kaplan turbine and propeller shaft turbine .These types of turbines are used for comparatively  low heads and high discharge  requirement .

TYPES OF TURBINE IN FLUID MACHINERY WITH SPECIFICATIONS 

  The different type of fluid machinery turbines with certain specifications can be summarised in the following table -

 CONCLUSION 

  Hence ,the different types of turbine used in the fluid machinery section are discussed above with their  specifications .There are many other turbines also such as gas turbines ,steam turbines ,wind turbine which are not discussed here .
