Development of the vapor film thickness correlation in porous corrosion deposits on the cladding in PWR

open access: yesNuclear Engineering and Technology, 2022
The porous corrosion deposits (known as CRUD) adhered to the cladding have an important effect on the heat transfer from fuel rods to coolant in PWRs. The vapor film is the main constituent in the two-phase film boiling model. This paper presents a vapor

Film forming behavior in thin film lubrication at high speeds

open access: yesFriction, 2017
The film forming condition may transit into thin film lubrication (TFL) at high speeds when it is under severe starvation. Central film thicknesses and film thickness profiles are obtained via a technique of relative optical interference intensity. These
