▶️Francis turbines are mixed flow reaction turbines. They are used in many hydroelectric plants because they can be used over a wide range of pressures and flow rates.
Pumped storage power stations use Francis turbines because the runner can act as both a hydraulic pump and hydraulic turbine.
How it Works
Water flows into the scroll case from the penstock. Water then flows through the wicket gate to the turbine runner. The water enters the runner radially and is discharged axially, because of this, Francis turbines are classified as mixed flow turbines.
After discharge from the runner, the water enters the draft tube then the tail race.

The graph at time mark 4:46 comparing Pelton to Francis to screw propellers was most informative. That was something not seen elsewhere and very helpful.

U were the best teacher than a book and professor because non of them can explain in such detail with 3d concept..thank u a lot

@AdamScheibe 8 месяцев назад

Thank you, this really helped me with my science studies!

@ranadev6279 Год назад

Thanks for the excellent illustration 🙏

@jonbarron3279 5 лет назад

Spectacular Videos! Love the 3D demos. By any chance can you post any videos of Super Turbo Turbines or perhaps even Steam/Gas Turbines. Thanks! And again, Great videos.

The guide vanes should be turned toward the francis turbine, how they are place in your graph, it causes that water crash againt them instead of going directly through the turbine following the curve of the vanes. This placement of guide vanes could potentialy cause damage to the turbine due to cavitation created by the lack of pressure.

Thank you for making it easy for us to understand. Please also include a video explanation on velocity triangles of Francis, Kaplan and Pelton turbine to calculate various parameters like hydraulic efficiency etc

Is there a small size that produces 5 megabytes ... or one megabyte? How much does a cubic meter of water need per second ... and how much is it worth in dollars ...

@felixknowloveyoudlovetokno2324 Год назад

Excellent explanations and demonstrations, thanks very much!

Hello, I am doing a thesis on hydroelectric power plant design, but I could not find a clear enough source. If there is a source that explains the principles of hydroelectric power plant design step by step, could you suggest you know?

@bhawanrawat2723 Год назад

Is there a video how it pumps the water up and are there smaller francis turbines and how small

Hello. Great video! I am trying to build a hydraulic system in Africa where we use 220V system instead of 110V. I want to use the hydraulic system from a well or in tank to produce electricity. Which turbine do you recommend I use? I want to be able to power a fridge, A.C, washer, microwave all the heavy loads. Do you have a generator or runner in mind? Would I need a battery or an inverter? If so, what kind?do you inn is a co oany that sells hydraulic system altogether (turbine, generator, battery, inverter etc) instead separately? Sorry for all the questions. Thank you for your help

@doblez241 4 года назад

The first you need is a difference of height from were you take the water and the place you will pour it.. as more difference in height better.. do you have that possibilitie?

@danielsequeira189 6 месяцев назад

Hello! Can someone please explain how to arrange and operate a Francis turbine to work as a pump?

@user-bc6cs7xe9q 4 года назад

How much is this in dollars? The design ... can address the company and know its specifications .. yet it generates electricity and does it have sizes. ... thank you very much ....

Do you have a link showing more information on the wicket gate system.

@savree-3d 3 года назад

At the moment, no. But good idea for the future.

@gaeb-hd4lf 3 года назад

Why is it a reaction turbine? Since the movement is caused directly by the water hitting the blades...

@markhonea2461 2 года назад

Very surprising that the narrator is describing the water direction incorrectly, initially. Does he not analyze a video before posting it? Unless I entirely misunderstand this thing. I still give it a 👍

@offgridmangogrower 8 месяцев назад

Can anyone point out a source for smaller Francis turbines…in the less than 50 gpm range….thanks

@shubop3199 4 года назад

Sir this is mixed flow turbine. But how water leaves in francis turbine with radial discharge at outlet? Please ans

@shubop3199 4 года назад

@@savree-3d U dint got my que This is modern Francis turbine with mixed flow But earlier there was Francis turbine with radial outward discharge How it occurs? *My english is not good

@Learnwithme.07 3 года назад

Runner is the only rotating part of the turbine. How is it connected to the non rotating parts? I mean it can't be hanging in the air.

@derBene 3 года назад

Probably with a bearing. "Francis turbine parts" at "en.wikipedia.org/wiki/Francis_turbine"

@KirtFitzpatrick 2 года назад

Why does the turbine spin in the opposite direction to the water flow in the scroll case? Intuitively it would seem more efficient to have it spin with the flow so that's got me scratching my head a bit.

@KirtFitzpatrick 2 года назад

Oh, it's a mistake in the video's 3D model.

Why is it said that a pure radiation turbine can't produce work.??

@piyushsemwal5142 5 лет назад

Sorry,I mean pure reaction turbine..

@simonbowman6206 2 года назад

Why are there no multi stage turbines ?? Answer the tech is available from RDP MARINE AUSTRALIA The techs will say the issues are turbine surging OR to much backpressure OR the dissolved gasses issue ALL are nonstarters So were is the price drop you can have by fitting this item ?? YES YOUKNOW WHY
