Getai Hydropower is one of the leading Pelton Turbine manufacturers. Our Pelton Turbine Generator, Pelton Turbine Efficiency, Pelton Runnerhas high quality and competitive price, and you can see the Application Of Pelton Turbine.
CFD analysis for Pelton turbine is performed in order to predict the turbine performance. The head loss in the collecting pipe and injector assembly is calculated based on CFD analysis results.
The relation of needle stroke and flow also can be calculated. CFD analysis can improve injector and nozzle design to reduce head los. The flow curve relative to needle stroke can be drawn based on analytical data.
CFD analysis can simulate the whole procedure which flow coming into and outgoing from bucket. The flow visualization can clearly show whether water flow outgoing from bucket pressure side hit the bucket back side. Such flow situation will cause more hydraulic loss and should be avoid during runner bucket optimum design process. The torque generated by runner and pressure distribution in the bucket can be calculated based on CFD analysis results. Turbine output and efficiency is finally predicted for various operating points.
Shenyang Getai Hydropower Equipment Co.,Ltd main products: Pelton Turbine, Francis Turbine, Kaplan Turbine, Tubular Turbine, Pelton Turbine Generator, Francis Turbine Generator, Double Francis Turbine, Pelton Turbine Formula, welcome to our factory!
The possible location of cavitation can be predicted based on the pressure distribution in the bucket. The phenomena of cavitation should be avoided in the back tip of splitter by optimum design for back shape of splitter.
