SINOPSIS

A measurement was made of stream wise velocity fluctuation in a fully developed turbulent flow in an eccentric annulus. The experiment was performed utilizing two annular ducts of different radius ratios 0.308 and 0.48; in each case the eccentricity was varied from 0.25 to 0.75. The result indicates that the radial distribution of the relative turbulence intensity has a minimum value in the central region between inner and outer tubes. The variation of the relative turbulence intensity against φ has a peak value near φ = 3π/8, where φ is the circumferential coordinate of the bipolar coordinate system. The location of the minimum turbulence intensity approaches the radial position nearest the outer tube wall when the value of φ is close to 3π/8. Those results indicate that there is some difference between two regions of φ < 3π/8 and φ > 3π/8.
