Abstract:V okviru projektne naloge smo raziskovali, v katerem cevnem sistemu pri hidroelektrarnah prihaja do najmanjših izgub. Voda iz zbiralnikov, ki na koncu vsake cevi poganja turbino, je pogosto razdeljena s pomočjo različnih oblik razdelilnikov na individualne turbine tako, da pride do minimalnih izgub. Za realizacijo te naloge so bili podani robni pogoji in določene konfiguracije cevnih sistemov. Hidravlične izgube, podrobneje lokalne izgube razdelilnikov, se določajo s pomočjo preizkusov, zato smo uporabili podatke iz predhodno izdelanih preizkusov.

Title:Hydraulic losses in manifolds - Comparison predetermined configurations
Abstract:During my project work, we examined which pipe systems, at a hydroelectric power plant, have lower energy losses. The engine water is usually distributed just before the power house through manifolds, to the individual turbines, in such a way that the energy losses are minimal. To realize this task, the boundary conditions were set for the pipe system and specified in the individual tubular structures. The loss of hydraulic manifolds one gets mainly by the hydraulic model test, so we used data from a previously made tests.
Keywords:local losses, manifold, turbine, laminar, turbulent flow, energy losses
