What Are the Ideal Parameters for Designing a Pelton Wheel?

Click For Summary
SUMMARY

The ideal parameters for designing a Pelton wheel include bucket width, width-to-length ratio, number of buckets, and nozzle diameter, which are all dependent on the wheel's size. Key resources for further information include the Wikipedia page on Pelton wheels and "The Micro-Hydro Pelton Turbine Manual" by Jeremy Thake, which provides comprehensive guidance on building Pelton turbines. The relationship between the number of buckets and wheel diameter is crucial, as it affects the wheel's operational speed and efficiency. Understanding these parameters is essential for replicating successful hydropower turbine models.

PREREQUISITES
  • Understanding of Pelton wheel design principles
  • Familiarity with hydropower turbine mechanics
  • Knowledge of fluid dynamics
  • Basic engineering design skills
NEXT STEPS
  • Research the relationship between bucket number and wheel diameter in Pelton wheels
  • Study the efficiency calculations for Pelton turbines
  • Explore water jet design and control techniques for hydropower applications
  • Read "The Micro-Hydro Pelton Turbine Manual" by Jeremy Thake for detailed construction guidance
USEFUL FOR

Engineers, hydropower enthusiasts, and students in turbomachinery looking to design or replicate Pelton wheel turbines for hydropower applications.

Would like to replicate a project we did in school for Turbomachinery class, which was to build a functioning hydropower turbine model. We were given the varous ideal parameters like bucket width, width to length ratio,number buckets and nozzle diameter based on size of wheel. Anyone know of any good links that have this info?

Anyone know the relationship between number of buckets for a wheel of particular diameter? Is it related to speed of wheel?
 
I had a paper from a turbomachinery class but I can't seem to find it. It had pretty much all you're looking for, damn clutter. I'll keep an eye out.

Search Amazon or your favorite book store for this:

"The Micro-Hydro Pelton Turbine Manual," by Jeremy Thake.

This will tell you everything you need to know to build your own Pelton turbine - from scratch - of any size. The book was written to assist people trying to bring hydro power to the third-world, using the manufacturing capabilities available on location. The book includes some theory, sizing information, efficiency calcs, details of water jet design/control, bucket shape/size/orientation/material, and so on. Very complete.
