The estimation of the damaged part size could be conducted by using a relationship between the value of pressure decay rate and the size of the damaged part, since pressure decay rate performs as a good indicator for the molar flow of air leakage or diffusion airflow. This study presents the development of a predictive model for estimating the air leakage through a defect and its contribution to pressure...
An alternative ultrafiltration membrane integrity test utilizing magnetic nanoparticle as a surrogate has been investigated in previous studies, but the absence of a feasible estimation model for the degree of membrane damage causes that this simple membrane integrity test would be not applied easily. This study proposed a calculating model to predict membrane defect size, and investigated the theoretic...
