Abstract: Abstract Fuel rods, one of the most important components in the nuclear reactor core, are usually supported by spacer grids along the axial direction. Since those fuel rods are long and slender, flow-induced vibration (FIV)… read more here.

Abstract: Early studies of the flow in rod bundles with spacer grids suggest that the pressure drop can be decomposed in contributions due to flow area variations by spacer grids and frictional losses along the rods.… read more here.

DOI: 10.1016/j.nucengdes.2020.110685
Abstract: Abstract In the dispersed flow film boiling (DFFB) regime, which exists under post loss-of-coolant accident (LOCA) conditions in PWRs, droplet dynamics play a critical role in heat transfer. The DFFB regime is characterized by a… read more here.
