The analyses of kinematic process of the ”helium blanketing effect (HBE)” were performed. With the simulation of the kinematic process the authors got a better understanding of the mechanism of HBE: HBE is a diffusion limited mass transfer process
the existence of line limitation is the main factor leading to the appearance of HBE. The ”bulk flow”(BF) model proposed by Ortman could predicate the blanketing pressure
however
It did not describe the kinematic process of Hydrogen absorption.
