Abstract

•Enclosure-width effects on heat transfer characteristics for low Prandtl-number buoyancy-driven flow systems are investigated.•The time-averaged and hot-wall-spatially-averaged heat transfer exhibits cascade-like behavior, which shows differently from those for high-Pr fluids.•Locally, those heat transfers peaks at a few locations, and these peaks travel cyclically as time elapses.•The primary mechanism governing these phenomena is referred as the generation and the annihilation of vortices, which are induced by various flow instabilities that are subsequently affected by the aspect ratio.•The present study serves as a sequel of a previous high-Pr investigation.
