Abstract:Namen diplomske naloge je bil analizirati pojav sekundarnega toka v vstopni cevi radialnega ventilatorja, ki se pojavi pri obratovanju izven preračunske točke. V ta namen smo izdelali merilno napravo za merjenje obodne komponente hitrosti toka v cevi. Naprava je izdelana kot anemometer s ploščatimi lopaticami, postavljenimi vzporedno z osjo cevi. Kot zasuka smo merili z magnetnim enkoderjem. Zajemanje in obdelava rezultatov so bili izvedeni v programu LabVIEW in Excel. Pridobljene rezultate smo grafično ponazorili v okolju MS Excel. Tako smo prikazali kako se parametri, ki smo jih pridobili s pomočjo magnetnega enkoderja vedejo ob različnih vrtilnih frekvencah radialnega ventilatorja in ob različnih obratovalnih pretokih zunaj preračunske točke. Rezultati se skladajo z predpostavkami, ki smo si jih zadali na samem začetku raziskovanja.

Title:Measuring the circumferential component of the flow velocity in the pipe
Abstract:The purpuse of the thesis was to analyze the phenomenon of secondary flow in the inlet pipe of a radial fan, which appears at the operation outside the calculation point. For this purpuse, we created a measuring device that measures the component of a circumferential velocity. This device is made as an anemometer with flat blades, which are parallel with the axis of the pipe. The rotation angle was measured with magnetic encoder. Results were captured and processed in programs LabVIEW and Excel. We graphically illustrated the obtained results in MS Excel. The obtained results show how the parameters behave at different velocities of the radial fan and at different operating flows outside the calculation point. The results are in line with our assumptions that were set at the beginning of a research.
Keywords:Secondary flow, centrifugal ventilator, anemometer, power spectral density, magnetic encoder
