A temperature-jump thermal resistance, based on results from Lin & Willis 1979, was implemented at the gas/solid interfaces of a three-dimensional computational fluid dynamics model of a 7 × 7 array of heated rods within a square-cross-section press

During vacuum drying of used nuclear fuel (UNF) canisters, helium pressure is reduced to as low as 67 Pa to promote evaporation and removal of remaining water after draining process. At such low pressure, and considering the dimensions of the system,
