Sanjivani Rural Education Society’s Sanjivani College of Engineering, Kopargaon-423 603 (An Autonomous Institute, Affiliated to Savitribai Phule Pune University, Pune) NAAC ‘A’ Grade Accredited, ISO 9001:2015 Certified Department of Mechanical Engineering Subject:- Turbo Machines T.E.Mechanical UNIT 1 :- Introduction to Turbo machines Purushottam W. Ingle Assistant Professor
- 2. 1 Turbo machines basics Turbomachinery, in mechanical engineering, describes machines that transfer energy between a rotor and a fluid, including both turbines and compressors. P.W.Ingle Department of Mechanical Engineering 5/18/2021 Turbine transfers energy from a fluid to a rotor, a compressor transfers energy from a rotor to a fluid
- 3. 1 Turbo machines basics These two types of machines are governed by the same basic relationships including Newton's second Law of Motion and Euler’s impulse momentum equation . P.W.Ingle Department of Mechanical Engineering 5/18/2021 Centrifugal pumps are also turbomachines that transfer energy from a rotor to a fluid, usually a liquid, while turbines and compressors usually work with a gas and hydraulic turbines works with a fluid like water.

- 10. 1 Comparisons of Turbomachines with positive displacement machines P.W.Ingle Department of Mechanical Engineering Positive Displacement Machines Turbomachines Involves thermodynamics and mechanical actions between nearly static fluid and slow moving surface, volume change cause pressure change. Positive Displacements machines are low speed machines. These machines have low volumetric efficiency Involves thermodynamic and dynamic actions between continuously flowing fluid and rotating element, the pressure change occurs primarily by means of dynamic actions of rotating elements . Turbomachines are high speed machines. These machines have high volumetric efficiency 5/18/2021
- 11. 1 Comparisons of Turbomachines with positive displacement machines P.W.Ingle Department of Mechanical Engineering Positive Displacement Machines Efficiency of conversion is high. Positive displacement machine like reciprocating compressor is a low speed isothermal machine. Turbo Machines Low Turbomachine like centrifugal compressor is a high speed adiabatic machines 5/18/2021
