Lecture - 1 (Introduction of hydropower turbines)
Turbines
Hydropower turbines are the rotary Machines which convert Kinetic and pressure energy of water (or we can say that dynamic and static head of water) into mechanical energy.
Some turbines convert only kinetic energy or dynamic head of water into mechanical energy and some turbines uses both kinetic energy and pressure energy of water into mechanical energy. Right now it's little bit confusing but dont worry we will have a detailed discussion on each and every points in my upcoming lectures.
Classification of hydropower turbines
based upon energy available at inlet to Runner
- Impulse turbines
- Reaction turbines
Based upon direction of flow of water with respect to Runner
- Tangential
- Axial
- Radial
- Mixed
Based upon specific speed
Based upon head and discharge
- For high head and low discharge - PELTON TURBINE
- For medium head and medium discharge - FRANCIS TURBINE
- For low head and high discharge - KAPLAN TURBINE and PROPELLER TURBINE
Before going directly to Turbines we will study impact of jets under different conditions, so that we can have better understanding of turbines.
