文摘
- •
A numerical approach is used to model permeability of defective barrier coating.
- •
Effect of random defect distribution on coating permeability has been investigated.
- •
Non-symmetrical permeability distribution is observed due to interaction among defects.
- •
Normal distribution is recovered when high defectiveness is considered.
