Analysis of fluid flows in tubes of variable cross-section by LDA
Analiza toka fluida kroz cevi promenljivog poprečnog preseka pomoću LDA
Abstract
In this paper, the possibilities of laser Doppler anemometry (LDA) are stated. Problems, that appear in LDA application on circular cross section tubes of 1) constant and 2)varying diameter, due to refraction of laser beam. Calculations of measurement errors, for mentioned problems, and methods for the correction of the measurement results are exposed. Finally, the results of application of those corrections are presented.
U radu su navedene mogućnosti laser Dopler anemometrije (LDA). Objašnjeni su problemi, koji se javljaju u primeni LDA kod cevi kružnog poprečnog preseka 1) stalnog i 2) promenljivog prečnika, usled prelamanja laserskog snopa. Izloženi su proračuni grešaka merenja, koje se javljaju zbog pomenutih problema i postupci korekcije rezultata merenja. Na kraju su predstavljeni rezultati primene tih korekcija.
