Description
The effect of curvature on the distribution of turbulent eddy viscosities in the wall subchannel of a CANDU bundle was demonstrated using the results obtained in a straight-wall subchannel (a subchannel bounded by a straight wall and a rod) and an annulus. The curvature reduced the anisotropy factor of turbulent viscosities from that in a straight-wall subchannel, but this factor was higher than that in a pipe. Correlations for the turbulent intensities at the narrow gap between the pressure tube wall and the fuel rod were developed. These correlations showed good agreement with the experimental data obtained in an up-scale model of the 37-element bundle. (Author) 13 refs., 8 figs
