Release of water trapped in damaged fuel subsurface voids

Abstract

of t h e release of water trapped i n subsurface voids during the vacuum drying f o r damaged f u e l. vapor, f i v e flow models a r e developed based on the k i n e t i c theory of gases. pressure provides the driving force f o r crevice water removal. Gas flow is divided i n t o three types: viscous flow, molecular flow, and s l i p flow i n the t r a n s i t i o n range. t h a t measured moisture release from the whole element drying s t u d i e s currently i n progress includes any water t h a t may be trapped i n subsurface voids.
