摘要：
One of the effective ways to improve the heat transfer of single-phase fluid is to rotate the fluid in the channel. In this paper, a numerical simulation was carried out to study the heat transfer characteristics of supercritical water in annular channel with helical ribs. Fluid-solid coupling model was established in the simulation, taking V. G. Razumovskiy's experiment as a reference. The results showed that the existing of helical ribs can improve the heat transfer in annular channel, but the effect is not obvious under normal condition. The effect of ribs number and pitch on heat transfer characteristics is important, which has to be considered in simulation and experiment. In addition, heat flux and mass flux have effects on circumferential non-uniformity of temperature.
