Abstract
U radu su istražene karakteristike modela Pelton turbine. Promatrane su karakteristike idealne i stvarne snage, te idealne i stvarne iskoristivosti u ovisnosti o dva parametra: kutnoj brzini okretanja modela turbine i bezdimenzijskom omjeru obodne brzine kola turbine i brzine mlaza vode na izlazu iz mlaznice. Karakteristike modela Pelton turbine izvedene su iz rezultata mjerenja tlaka pumpe, protoka, brzine okretanja modela turbine i Momenta sile kojeg model turbine ostvaruje. Za svako od mjerenja objašnjeni su mjerni lanci uz pomoć kojih su izmjerene vrijednosti dobivene. Dimenzijskom analizom dobiveni su bezdimenzijski parametri za dani model Pelton turbine. Rezultati su prikazani u obliku dijagrama sa prikazom mjernih točaka i regresijskih krivulja koje pokazuju funkcijsku vezu u rezultatima mjerenja. Pogreška u rezultatima mjerenja i izvedenim veličinama snage i iskoristivosti ocijenjena je uz pomoć relativne pogreške. Pritom je relativna pogreška izračunata za svaki mjerni lanac, a relativna pogreška izvedenih veličina je izvedena iz relativnih pogreški individualnih mjernih lanaca.
Abstract (english)
This thesis presents the research on the performance characteristics of a model of Pelton turbine. The characteristics observed are ideal and real power of the turbine model and ideal and real efficiency of the turbine model in relation to two parameters: angular velocity of the turbine model, and the non-dimensional ratio of tangential speed of turbine blades over the speed of water exiting the nozzle. Performance characteristics were derived from measurements of pump pressure, flow, rotational speed of the turbine model and the torque produced by the turbine model. For each of the measurements taken the measurement chain used to measure it was explained. Dimensional analysis was used to derive non-dimensional parameters for the given model of Pelton turbine. The results are shown in the form of diagrams with measurement points and regression curves showing the functional relation between the measured quantities. The measurement error in calculations of power and efficiency was expressed in the form of relative error. The relative errors were calculated for each measurement chain and the relative errors of derived quantities were derived from relative errors of individual measurement chains.
