“…The highest value of the swirl ratio was 1.12 at the downstream of the MRV. For the FSV, on the other hand, the maximum swirl ratio was 0.2314, which has the similar value compared to the previous studies [10,12]. As shown in Fig.…”

“…Fig. 10 shows the swirl ratio of the SG, FSV, and MRV with comparison of previous studies [10,12]. The swirl effect was not observed in the SG, because there was no flow obstacle at the downstream of the vane.…”

“…They showed that the lateral velocity at the downstream of the mixing vane changed the void fraction distribution; thus the CHF was enhanced. On the other hand, types of split-type spacer grid and swirl-type spacer grid have been investigated in a 5 Â 5 rod bundle using LDV measurements for the CFD benchmark test [12]. Lateral velocity, mixing and swirl ratio, and secondary flow intensity at the downstream of the vanes were analyzed.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
