dc.description.abstractIn this study, we perform Direct Numerical Simulations (DNS) of fully developed turbulent flows in eccentric annuli having different diameter ratios. Annuli of unit eccentricity, and diameter ratios of 0.2591 and 0.1395 have been investigated, for a Reynolds number of 14600 based on the bulk velocity and outer wall diameter. This study aims to investigate the different flow characteristics, including the effect of the diameter ratio on the pressure gradient and the friction factor. Furthermore, this work confirms the presence of mean secondary flow for the configurations considered, while its effect on the flow characteristics and vortex structures is discussed in relation to the diameter ratios investigated.en
