Abstract. The aim of this paper is to investigate on the turbulence
structure and on the statistical properties of vortex shear layer in swirling
flow in pipes and in a diffuser. Accordingly, for the experimental measuring
of statistical properties, hot-wire anemometry has been applied with the
use of three-sensor probe, and with digital data processing and statistical
analysis of measured data.
SAVREMENI PROBLEMI U TURBULENTNIM VIHORNIM
STRUJANJIMA
Cilj ovog rada je da se istraži struktura turbulencije i statističke osobine
vrtložnog smičućeg sloja u vihornim strujanjima u cevima i u difuzoru.
Shodno tome, za eksperimentalna merenja statističkih veličina korišćena
je anemometrija sa vrelom žicom korišćenjem trosenzorskih sondi, sa digitalnom
obradom podataka i statističkom analizom izmerenih podataka.
