TL;DR: In this article, the authors numerically explored liquid fall induced gas entrainment in an FBR hot pool, and proposed a passive strategy to mitigate gas entraining in the form of a circumferential baffle plate.

TL;DR: In this article, a circular cylinder mounted on a flat plate normal to the flow direction is numerically simulated to obtain the detailed spatio-temporal dynamics of wake vortices revealed through the velocity and pressure data.

TL;DR: 3D numerical simulations on a scaled down model of the DAF design were analysed and design modifications have been proposed by using a perforated tube for water extraction and are found to be satisfactory.

TL;DR: In this paper, a fundamental approach towards quantification of thermal and pressure loadings on RCB during a core disruptive accident (CDA) has been described, where mathematical models have been derived from fundamental conservation principles towards determination of sodium release during a CDA, subsequent sodium fire inside RCB, building up of positive and negative pressures inside RCBs, potential of in-vessel sodium fire due to failed seals and temperature evolution in RCB walls during extended period of containment isolation.

TL;DR: Koncar et al. as mentioned in this paper focused on finding an optimum performance of one such finger mock-up through systematic computational fluid dynamics (CFD) studies, which showed that addition of sectorial extended surfaces (SES) enhances heat removal potential with minimum pumping power.
