dc.description.abstract | Prikazana su veoma precizne, originalne sonde sa zagrejanim vlaknima visoke prostorne i vremenske rezolucije i kalibracioni metod za turbulentna eksperimentalna istraživanja. Ovaj metod zahteva pozicioniranje V-sonde pod određenim uglom u odnosu na uniformnu brzinu mlaza otvorenog aerotunela. Iz dobijenog signala formira se kalibraciona matrica. Ocene odgovarajućih eksperimentalnih krivih su oblika Čebiševljevih polinoma, čime se vreme proračuna mernih tačaka značajno smanjuje. Ovaj kalibraciono-merni postupak zahteva manje pretpostavki nego u slučaju standardnih metoda zasnovanih na Kingovom zakonu. | sr |
dc.description.abstract | Sophisticated equipment with unique hot wire V-probes, with high time and spatial resolution, and computer-aided calibration method for turbulence experimental research are described. This method requires the V-probe to be pitched in the uniform jet of the unique open calibration air tunnel at several velocities. From the outcome signal, a calibration array can be generated. Corresponding experimental curves are fitted with Chebishev polynomials, which decreases computational time. This method requires fewer assumptions than one based on the King's law. | en |
