Runner Design for a Francis Turbine

please contact bfay@frenchriverland.com

Dear Mr. Sargam:

Francis runner design is covered in Nechleba, Kovalev and Daugherty, to name a few classic authors. You should spend more time on my sidebars, as it is also detailed in:

http://frenchriverland.com/hydraulic_turbines.htm

and

http://frenchriverland.com/design_of_small_water_turbines_for_farm_and_small_communities.htm

Good luck in your endeavours.

Sincerely,

Bill Fay

These volumes have a sections on Francis design.

Dear Aron: Sometimes what you seek is disquised!!! The turbine manufacturers were paranoid schizophrenics when it came to their design procedures. But!!!! a propellor, is a propellor, is a propellor, is a propellor and propellor design is widely covered. I suggest the following learned treatises on the subject: 1) Detailed Design of Marine Screw Propellers", by Douglas H. Jackson. Originally published by Sir Isaac Pitman & Sons, Ltd., London, this is a complete unabridged reprint from Wexford (2007 softcover, 100 pages with illustrations). Large format book - Dimensions are 8 1/2 x 11 inches.

ISBN: 1427614016

2) Hydrodynamics of Ship Propellers - P. Andersen, Cambridge Ocean Technology Series , No 3.

This book deals with flows over propellers operating behind ships, and the hydrodynamic forces and movements that the propeller generates on the shaft and on the ship hull. The first part of the book is devoted to fundamentals of the flow about hydrofoil sections and wings, and to propellers in uniform flow, with guidance for design and pragmatic analysis of performance. The second part covers the development of unsteady forces arising from operation in nonuniform hull wakes. A final chapter discusses the optimization of efficiency of compound propulsors. Researchers in ocean technology and naval architecture will find this book appealing

3) Hydrodynamics of Ship Propellers

Synopsis: This book deals with flows over propellers operating behind ships, and the hydrodynamic forces and moments that the propeller generates on the shaft and on the ship hull. The first part of the book is devoted to fundamentals of the flow about hydrofoil sections and wings, and to propellers in uniform flow, with guidance for design and pragmatic analysis of performance. The second part covers the development of unsteady forces arising from operation in nonuniform hull wakes. Both cavitating and noncavitating propellers are considered, and the problem of a noncavitating, wide-bladed propeller in a wake is treated by a new and completely developed theory. A final chapter discusses the optimization of efficiency of compound propulsors. The authors have taken care to clearly describe physical concepts and mathematical steps. Appendices provide concise expositions of the mathematical techniques used.

Description: (560 pages) Although the propeller lies submerged out of sight, it is a complex component in both the hydrodynamic and structural sense. Marine Propellers and Propulsion fulfils the need for a comprehensive and cutting edge volume that brings together a great range of knowledge on propulsion technology, a multi-disciplinary and international subject. The book comprises three main sections covering hydrodynamics, materials and mechanical considerations, and design, operation and performance. The discussion relates theory to practical problems of design, analysis and operational economy, and is supported by extensive design information, operational detail and tabulated data. Fully updated and revised to cover the latest advances in the field, the new edition now also includes four new chapters on azimuthing and podded propulsors, propeller-rudder interaction, high-speed propellers, and propeller-ice interaction The most complete book available on marine propellers, fully updated and revised, with four new chapters on azimuthing and podded propulsors, propeller-rudder interaction, high-speed propellers, and propeller-ice interaction A valuable reference for marine engineers and naval architects gathering together the subject of propulsion technology, in both theory and practice, over the last forty years Written by a leading expert on propeller technology, essential for students of propulsion and hydrodynamics, complete with online worked examplesThe Early Development of the Screw Propeller. Propulsion Systems. Propeller Geometry. The Propeller Environment. The Wake Field. Propeller Performance Characteristics. Theoretical Methods - Basic Concepts. Theoretical Methods - Propeller Theories. Cavitation. Propeller Noise. Propeller-Ship Interaction. Ship Resistance and Propulsion. Thrust Augmentation Devices. Transverse Thrusters. Azimuthing and podded propulsors. Waterjet Propulsion. Full-Scale Trials. Propeller Materials. Propeller Blade Strength. Propeller Manufacture. Propeller Blade Vibration. Propeller Design. Operational Problems. Service Performance and Analysis. Propeller Tolerances and Inspection. Propeller Maintenance and Repair.

and last but not least!!!

8) Theory of Wing Sections: Including a Summary of Airfoil Data (Dover Books on Physics)

Publisher: Dover Publications
Binding: Soft cover

9) Basic wing and airfoil theory, Alan Pope, Publisher: McGraw-Hill
Publication Date: 1951

Although the older theory covers only unducted propellors, the newer texts cover both ducted and guided props, such as thrusters. I would think this theory could be directly applied to the new free flow hydro turbines that seem to be the new fad here in the States.

Good luck on your studies!! The future looks very encouraging for all of us. If you are ever in the Boston area, please drop by and stay for a few days with Carol and I.

Dear William,

Thank you for the quick reply and the link to the book, it's been very helpful. I'm now reading it, and it explain a lot of reasoning I can use to understand the working of a turbine.

It's actually my second work, in previous thesis, I build a propeller turbine with an propeller of a 40pK boat and recuperation material in Surinam. It worked but the efficiency was a bit low, and the "jackie Brown" as we called her is still standing at the university there.

That's why I want to work on this to get a high efficiency as possible. For that I need the theory for the effective design of a propeller, as my case is for a very low head. I'm not through the book yet and I hope there's something about the right angles and the curvature of the blade in the work. I also have the part you put online of the design by Kovalev, do you by any chance also have the complete work?

And If you have a work on the theory of the design of a propeller, it would be wonderful if you could pass it through.

Thanks in advance,

Kind regards,

Aron Buyle

Ps: the problem is that there isn't much information about the theory to find. The only good info I found was on your site. I'm very grateful for that.

and

i think i've finally got what i was looking for.

the design procedure is given in the book written by Nechleba.

thanks a lot for all the info

cheers!!!

Dear Mr. Sargam:

Great!! I am glad I could be of assistance. In case you need it, I included the original analysis on the subject in:

April 11th, 2009, added scanned textbook, Hydraulic Motors by M. Bresse as translated by F. A. Mahan, July 1869. Also added links to Part I and Part II of the 1880 US Census, Water Powers of the United States
