“…The average Nusselt number of the system with ribs reached as high as 1.4 times than that without ribs. Jeng et al [10] also experimentally investigated the heat transfer characteristics in the annulus with an inner rotating rib-roughness cylinder under various rotational speeds and heat fluxes applied on the inner cylinder. Their results show that the heat-flux effect on the heat transfer was negligible.…”

“…Moreover, experimental and numerical studies of slits wall configuration geometry influence on flow distribution and heat transfer within a Taylor-Couette system, have surged due to the importance of increase heat transfer rate within a cylindrical annulus gap. The study by Jeng et al (2008) aimed at determining the heat augmentation in the annulus gap with an inner rotating rib roughness cylinder. The results showed that the cylinder ribbed surface improved the heat transfer compared to the plain model.…”

Heat transfer enhancement is by far an important component in the design of numerous industrial applications of Taylor-Couette flow including electric motors and particularly rotating machinery. To optimize the performances of these machines, superior knowledge of the fluid flow is vital to better estimate the heat transfer distribution. This study will specifically consider the effect the slit number and width possess on the distribution of turbulent Taylor-Couette flow and the resulting heat transfer correlation in the annulus of two concentric cylinders under varying conditions. A numerical simulation method is intended for the study using varying slit structure parameters of widths (2.5 ≤ w ≤ 7.5) mm and fitted with 6, 9 and 12 number of slits. The slit effect is then investigated under both isotherm and non-isotherm conditions considering the interactions between fluid flow regions in the mainstream area and the annulus. The small-scale vortex that appears in the annulus region improves the heat transferability between the fluid in the annulus and the main region as well as the heat transfer performance of the model with a gradual increase in Reynolds number.
