Optimizing of Simplyfeid Circular Distributional Pipe of the Vertical Pelton Turbine with 5 Nozzles.

This diploma thesis deals with hydraulic optimization of distribution pipeline for 5 nozzle Pelton’s turbine by using CFD. The thesis is a follow-up to a previous diploma thesis which deals with the possibilities to simplify existing distribution pipeline. A few simplified versions of distribution pipelines were solved and the results show which way we should proceed towards the right solution. The simplified distribution pipeline arises from given parameters and retains the same procedure of evaluation to give us the opportunity of comparing achieved results. Two new geometries of distribution pipeline were created. They were then modified to achieve optimal distribution of discharge in each nozzle. Other criteria used for comparison were static pressure and Coriolis’ number in specific slices inside pipeline. Last but not least a simple economical analysis for selected version of distribution pipeline was carried out on the basis of which we can see the manufacturing costs of the pipeline
