This web site will give you some vanki as to how to go about it: From Wikipedia, the free encyclopedia. The peak efficiency of a cross-flow turbine is somewhat less than a KaplanFrancis or Pelton turbine.

By using this site, you agree to the Terms of Use and Privacy Policy. The turbine geometry nozzle-runner-shaft assures that the water jet is effective.

These divide and direct the flow so that the water enters the runner smoothly for any width of opening. Water admission to the two nozzles is throttled by two shaped guide vanes.

Also a homeowner can more easily build a cross-flow turbine because the turbine blades are a simple shape compared to the complex buckets of the Pelton turbine, however you can buy a Pelton wheel only. Critical geometry of the cross-flow turbine.


It is, however, essential that the turbine, head and turbine speed are harmonised.

Design and calculations for the cross-flow turbine

The regulating device controls the flow based on the power needed, and the available water. Dimensions and power extraction capacity of the cross-flow turbine A cross-flow turbine is a type of turbine that is suitable for low head high flow applications. Chiudendo questo messaggio o continuando la navigazione, si presta il consenso al loro utilizzo. Views Read Edit View history. However, the cross-flow turbine has a flat efficiency curve under varying load. Unlike most water turbineswhich have axial or radial flows, in a cross-flow turbine the water passes through the turbine transversely, or across the turbine blades.

Cross-flow turbine

Low operating costs are obtained with the turbine’s relatively simple construction. Unsourced material may be challenged and removed.

The inspection door on the introducer allows an easy access inside the turbine. The water strikes the turbine blade rotating the whole turbine wheel. Please help improve this article by adding citations to reliable sources.

Cross-flow turbine – Wikipedia

The following image shows the passage of the water jet through the turbine. This page was last edited on 10 Marchat Another advantage is that it can often clean itself.


The blade’s edges are sharpened to reduce resistance to the flow of water. I am merely extracting from that document the relevant formulas that are turine for sizing the turbine.

You can visit their web site here: The turbine consists of a cylindrical water wheel or runner with a horizontal shaft, composed of numerous blades up to 37arranged radially and tangentially.

The guide vanes therefore act as the valves between the penstock and turbine. Mitchell is the original inventor of the turbine around When the water leaves the runner, it also helps clean it of small debris and pollution.

The leading edge of the blade should be at 30 degrees to the tangent at the point of contact. The machine is completely assembled, all the components are installed on a frame base utilized for fixing the whole group on the floor. Today, the company founded by Ossberger is the leading manufacturer of this type of turbine.
